Rationale of Particle Physics

Some dont like atomic and particle smashing. A few believe
the particles produced by the accelerators are just debris.
Many alternative modelers just ignore them. But how could you
ignore the evidences. I'm writing this to get arguments from the
particle physics critics why and how there may be a flaw in the
interpretation (if there is).

To gain perspective. Particle Physics is like magic with
mathematics. Imagine you collide two chairs together by
spinning each very fast tied to the center rotators. For
an instant after the collision. You can get a table or a
skateboard as long as the energy and momentum is
enough to produce it. This is what particles physics is
claiming. Actually. It's more elegant. For example.
The W boson weights about 92 GeV. If you can produce
an accelerator that can produce this much energy in
the collisions (via the concept of the corresponding energy
can be equalled to mass thing). You can produce the
W boson. As another example. High energy photon
collisions near charged system can produce the momentum
to produce electron-positron pair.. but this doesn't mean
electron is composed of photons. It's like energy can
be directly converted to mass and particles as in literally.

Has anyone got any problem with the concept above? Some
believe these particles such as the W boson is just debris
created out of the collision. Do you have other arguments
that can debunk the principle of particle physics?

The rationale for the creations of billion dollar particle
accelerators is to build more energy and momentum
to precipitate or materialize the particles. It is not to
break the particles apart revealing the deeper particle
constitutions. But to convert the energy out of it directly
to mass. For example.. colliding two chairs and expecting
it to produce skateboard for an instant. Don't you find
this a bit strange. Particle experiments show that these
particles are composed of the same energy as others,
but what is the deeper mechanisms involved.

Ultimately they tie it to the Big Bang. The purpose of
the accelerators is to see what would happen (like
what particles would be produced) if the energy and
momentum can be made closer to that produced in the
Big Bang. For example, in the concept of Symmetry
Breaking. Electromagnetism and the Weak Force is
one not far from the Big Bang. When the temperature
becomes colder and the energy and momentum becomes
less. They separate into electromagnetism and the weak
force. Ok. Can someone try to debunk this entire concept??
Could it be possible there is no Big Bang and the
accelerators findings can be interpretated in other ways?

Look. I think the whole concept of Particle Physics is
elegant. But from time to time.. I heard so many
counter-arguments from the disbelievers. So I wrote
this message to hear what the arguments are really
all about and to see how valid they may be.

It certainly is possible. The Big Bang is still theoretical and
intimately linked to GR being the final theory, which is disputed
by many in the community.

As for accelerators findings, it is thoroughly understood that
all unstable particles produced in high energy scattering collisions
eventually ultimately decay into stable electrons, positrons, protons
and neutrons, which are the lowest energy particle states for matter,
plus some gamma and neutrinos.

My personal view is that the resticted subset of stable massive
particles is consequently the most important set, since all stable
matter in the universe can be made up of nothing else.

Your guess is as good as anyone else's since everyone
is convinced that his own opinion is the best.

My suggestion is not to look for opinions or couter arguments,
but to dig yourself into the pile and decide for yourself what
you think is valid data, and than build from there.

Can you give an example of what you mean that the
unstable particles produced decay into stable electrons,
protons, etc.. Isn't it that all the resultant particles
created from collisions dissipated afterwards. If this
were possible. One could precipitate Gold in the accelerators.

If collisions can produce electron-positron pair. I wonder
what is the difference between the permanent electron
in existence and those produced by collisions. What I
mean to say is. How do you make the unstable electron
produced in the collisions become permanent. I still
haven't read the book "Introduction to Elementary Particles"
as I'm still thinking what is a better substitute for it
and it's quite expensive too.

Well. How about this. The accelerator experiments created
the necessary energy, but what is produced is moulded or
taken from the mind of the physicists themselves so when
a strong group suggested that a particle called vulcan
with certain mass exist. Latter experiment can produce
this vulcan particle out of thin air or energy (made from
the thoughts of the physicists mind themselves). And later
the programming becomes fixed and all accelerators worldwide
can produce such consistent results. Actually I heard others
suggest this. What's the 100% proof that this is not true
or can't be possible.

No unstable particle created artificially by high energy scattering
"dissipates" into thin air. They all decay into lower and lower energy
particles until some stable particle(s) is left, which cannot decay further.

The final stable product of muon or tau decay for example, is a simple
electron. The excess energy is deemed to escape as neutrinos.

Pi+ mesons cascade decay into muon, then electron plus neutrino.
Pi0 mesons can decay into two photons, or alternately into some
gamma plus a pair of electron-positron, and maybe a few other
sequences.

And so on for all other unstables particles that initially appear as
a result of high energy scattering.

If you go to a library and have a look at the CRC Handbook of
Chemistry and Physics, you will be able to see the sequence for
most of them.

They no doubt are also available on the internet.

> If this were possible. One could precipitate Gold in the accelerators.

There is a difference between complex atoms and elementary
particles. If you collide elementary particles, only the simplest
particles combinations are likely to occur.

There is no difference at all. They are the same.

There is no such thing. All electrons are permanent and identical,
irrespective of how the come into being. That is, unless a destructive
encounter causes them to convert to gamma, in positronium decay
for example, or to have their energy recombined into some other
particle in high energy scattering.

If you go to a used books facility, you'll be surprised at how
little you can pay for the most surprisingly advanced books
on all subjects, including high energy physics.

People die. Their whole personal libraries occasionally end up on
tables in flea markets.

This is something you will have to make your own opinion about.
Your hand and your keyboard are made of "something". What is it?

When you follow this trail, you always ultimately end up looking
at stable elementary particles.

No particle appears out of thin air in accelerators.

Consistent results from accelerators can only mean that large
quantities of energy always end up producing the same limited
set of outcomes.

It is for you to make up your own mind about this.

Is your hand real ? What is it made up of ?

Find the proofs yourself that will satisfy you. No one will be able
to convince you either way.

When I say, "it dissipates into thin air". I didn't mean the
energy just vanish but dissipates away by converting to heat
in the equipments or detectors for example without any stable
particles left. So there are stable particles left. I see. Ok.

Ok. I will find the information about their sequences and order
of decay. It is really so fascinating to see direct effect of
the interrelationships and interchangeability of energy and mass.

What I mean is. Suppose you use high energy photons and make
it connect near nucleus giving the right configurations to
produce electron-positron pair in instant. What would it take
to make the electron become permanent. Is there a way to suck
the positron away before the pair annihilated?

I like the strings concept where the photons are one string
and it splits into two when the pair is produced and turning
back to one string configurations as it floats in the q. vacuum.

What do you think about M-theory. If it's not true. How come
the mathematics has so many symmetries and so consistent
and so many coincidences too like gravitons appearing in
the right place, etc. Could M-theory be really it?? I'm so
tired of all alternative models that don't make any sense if
you would look deeper. I think it's possible M-theory is it.

I agree. Utterly fascinating.

What you need is just one real photon of energy exceeding
1.022 MeV that comes very close to a heavy nucleus. Its interaction
with the electric field of the nucleus will cause it to split and turn
up as a pair of opposite charge electron and positron moving
away from each other at the velocity determined by the energy
in excess of 1.022 that the incoming photon has.

Some talk about a second photon being required. They are referring
to a QED virtual photon that is a metaphor of the Coulomb interaction
with the nucleus, what I referred to above as the electric field of
the nucleus.

> What would it take to make the electron become permanent.

Only that the incoming photon have more than 1.022 MeV of energy
to start with.

> Is there a way to suck the positron away before the pair annihilated?

Both particles naturally fly away from each other if more energy than
the amount that converts to the mass of both particles (which is
0.511 MeV for each) is provided.

The positron created can annihilate with any electron in the vicinity,
not necessarily with the one that materialized with it.

Since the actual mechanics is not known, your guess is as good
as anyone else's.

Any self consistent theory will seem complete to those who
like them.

You will have to decide that for yourself.

Looking into each theory and discarding them one by one as
you find that they don't make sense on one point or other is the
only way to weed the hay stack and ultimately get to the
ones that make sense. Many do in specific areas and give satisfying
solutions to some extent. For example, QM, QED, relativistic
newtonian, SR, GR, Maxwell's wave theory and a few others.
The problem is that they don't all seemlessly fit together.

The final solution is to find a way for all the sensible pieces to fit
together in one coherent whole, even if it means modifying them
a little if required to allow the proper fit.

If no solution on record satisfies you, you may eventually come up
with a solution of your own.

No, stooopid.  One photon with energy greater than 511 Kev grazing a
heavy nucleus (for the electric field) does the job.

Indeed.  It would show a stunning lack of curiosity to dismiss the
collision products as "debris" without thinking there's real physics
there that should be explored.

But without some theory to interpret the data, it's not debris or anything
else, it's just inexplicable.

I would find it stranger to create a short-lived skateboard than to create
a short-lived particle.  The skateboard not only has more particles, those
particles have a particular arrangement amongst themselves.

That's one application.  But they're more directly concerned with testing
the standard model of particle physics, and alternatives like
supersymmetry.  You only read about the searches for new particles, but
most accelerator work has been measuring parameters of the theory or
studying the structures of things.

Yeah, they write about unification theories as if that's the only thing
physicists ever work on.  I don't know much about GUTs.

>Could it be possible there is no Big Bang and the

It could be possible that there was no Big Bang and the interpretation of
the accelerator findings were spot-on.  Particle physics can shed some
light on cosmology, but cosmolgy doesn't shed much light on particle
physics, and the forces don't have to be unified for the Big Bang to have
occured.

I don't pay as much attention to that crowd as I used to.

the answer is too simple
to be acceoted by 'sphisticated scintists':

energy is mass im notion*!!
thats all

so if it has mass than(nearly)
any conbination of itys
mass can be done

now the bigg fraud of say the W bosons
found in accelerators is that .....
*it is found only in the accelerator !! (:-)
not  a bit connected to the everydayreality)

trhe W for instance is a big pile
of acumulation of mass that comes
from the accelerator and not of single
electrons or Protons
it is may of them piling together!!
and i aleady claimed that many times.

all the best
