It was said in one reference, that except for higgs boson, 61 in 62
elementary particles predicted by Standard Model has been supported or
discovered experimentaly.
what is the 62 elementary particles?

What is the reference?  Are you sure there are 62?  I only get 43
counting a Higgs.  12 Gauge bosons, 12 leptons, and 18 quarks.

Whoops!  Forgot the anti-quarks.  So that gives 61 counting the Higgs.
What did I miss?

seems a bit subjective...
