This means that within the OPAL detector the W-bosons are never directly observed, only their decay products are measured. W bosons decay into two fermions. A can decay into a lepton and anti-neutrino or a quark anti-quark pair. The branching ratios for each of these ...

WebMeanwhile, only five bosons are responsible for all of the interactions between matter. They carry three of the four fundamental forces in nature: the strong force, the weak force and electromagnetism. The strong force is carried by the aptly named gluon. It holds quarks together to make protons, neutrons and more exotic large particles.

Their statistical properties are very different: no two fermions can be in the same state, but there is no such restriction on bosons. Bosons are particles with integer spin: WebBosons are sociable; they like to get together. As a rule of thumb, any atom with an even number of electrons + protons + neutrons is a boson. So, e.g., ordinary sodium atoms are bosons, and they can merge to become Bose-Einstein condensates. Left: Bosons are social; fermions are antisocial. Fermions, on the other hand, are antisocial.
