Hey folks, give me a little help with something. Leptons and quarks
are said to come in three "families" or "generations." If this were
applies to bosons, what would the families be? The electron, electron
neutrino, up quark and down quark are all in family one, these being
typical matter particles. My guess is that the photon and gluon would
also be in this family, since they are involved with the ordinary
matter particles. Does that seem sensible? What about the W^-, W^+,
Z^0 and higgs boson?
Doesn't quite work that way.
For one thing, we don't know why there are three generations of
fermions (quarks and leptons). We do know why there are as many bosons
as there are.
The fermions have several properties, and some of those properties can
be called different kinds of "charge". There's electromagnetic charge,
strong charge (sometimes called "color"), weak charge (sometimes
called "hypercharge") and gravitational charge (sometimes called
"mass"). The fermions can have more than one kind of charge.
Neutrinos, for example, have only weak and gravitational charge.
Electrons and muons have weak, gravitational, and electromagnetic
charge. Quarks have all four kinds of charge. Those charges determine
how they interact, and the bosons mediate those interactions. For
example, electrons and muons can radiate, absorb, or swap both photons
(electromagnetic bosons) and W and Zs (weak bosons).

-------------------
you dont have any experimental prof that Bosons
mediate anything
you found them only in a huge accelarator
and only there
all that mediating story for particles
is a nice fairy taile !!! 9on papers only )
