Question

How many parts of bosons particles?

Answer 1

Types. Bosons may be either elementary, like photons, or composite, like mesons. While most bosons are composite particles, in the Standard Model of Particle Physics there are five bosons which are elementary: the Standard Model requires (at least) one scalar boson (spin=0)

Answer 2

1 Photon. 2 Gluon (there are eight types of gluons) 3 Z boson. 4 W boson (actually two particles — the W+ and W– bosons) 5 Higgs boson (this one hasn't been found yet)
