Bosons and Mesons - Fundamental or Compound?

Click For Summary
SUMMARY

The discussion clarifies the classification of Bosons and Mesons within the framework of the Standard Model of particle physics. Bosons, including photons, gluons, and W and Z bosons, are defined as fundamental particles with integer spin. In contrast, Mesons are composite particles made up of a quark and an anti-quark, categorizing them as hadrons. The distinction is made that while Bosons can be fundamental, they can also appear in composite forms, as seen in Mesons.

The Standard Model defines Bosons, along with Fermions, as Fundamental Particles.

At the same time, Mesons, which include Bosons, are supposed to be a compound made up of a quark and an anti-quark.

So, which is it? Is a Boson a fundamental particle or a compound (ie.Hadron)?

Bosons and Fermions can be either fundamental or composite. The fundamental fermions are leptons and quarks. The fundamental bosons are photons, gluons, weak force carriers (W and Z), and gravitons (theoretical).
Bosons have integer spin, fermions have half-integer spins. For example mesons (quark + anti-quark) are bosons, while baryons (3 quarks) are fermions. Atoms may be bosons or fermions, depending on whether the number of neutrons is even (bosons) or odd (fermions).
