Question about particle physics in general

Click For Summary
SUMMARY

Fermions are defined as particles with half-integer spins (1/2, 3/2, etc.), while bosons are characterized by integer spins (0, 1, 2, etc.). Electrons are classified as fermions and cannot be subdivided into quarks or leptons. Mesons, despite being composed of two quarks, are classified as bosons due to their integral spin. The classification of particles is based on their spin properties rather than their roles as matter or force carriers.

PREREQUISITES
  • Understanding of particle physics terminology, specifically "fermions" and "bosons."
  • Knowledge of spin concepts in quantum mechanics.
  • Familiarity with the Standard Model of particle physics.
  • Basic comprehension of quarks and leptons as fundamental particles.
NEXT STEPS
  • Research the properties of fermions and bosons in quantum mechanics.
  • Study the classification of particles in the Standard Model of particle physics.
  • Explore the concept of spin and its implications in particle behavior.
  • Investigate the role of mesons in particle interactions and their significance in quantum field theory.
USEFUL FOR

Students and professionals in physics, particularly those focusing on particle physics, quantum mechanics, and the Standard Model. This discussion is beneficial for anyone seeking to clarify the distinctions between fermions and bosons.

So I read that fermions can be defined as "matter particles," while bosons can be defined as "force carrier particles." I read further that fermions can be divided into quarks and leptons.
However, apparently mesons are considered bosons, as a consequence of their spins. Does that mean that, despite being composed of two quarks, a fermion, mesons are bosons?

This categorization is incorrect, and is not general.

Fermions are "particles" with integral 1/2 spins, i.e. spin of 1/2, 3/2, 5/2, etc. An electron is a fermion, and it CANNOT be divided into quarks and leptons.

A boson has integral spin, i.e. 0, 1, 2, 3, etc. A photon is a boson, it definitely is not composed of 2 quarks.

So the particles defined by their spin, and not by whether they are matter particles or force particles?
