SUMMARY

The discussion centers on the mass of particles, specifically addressing the distinction between fermions and bosons. It is established that fermions possess mass while bosons, such as the Higgs boson, can also have mass but do not necessarily have antiparticle partners. The Higgs boson is highlighted as an example of a particle with mass that lacks an antiparticle counterpart. The conversation emphasizes the importance of understanding the Higgs mechanism and its implications for particle mass.

PREREQUISITES
  • Understanding of particle physics terminology
  • Familiarity with the Higgs mechanism
  • Knowledge of fermions and bosons
  • Basic concepts of antiparticles
NEXT STEPS
  • Research the Higgs mechanism in detail
  • Study the properties of fermions and bosons
  • Examine the role of antiparticles in particle physics
  • Explore the implications of massless particles, such as photons
USEFUL FOR

This discussion is beneficial for physicists, students of particle physics, and anyone interested in the fundamental properties of matter and antimatter.

I'm wonder what particles have mass. Is it true that only fermions have mass and bosons do not? Or is it true that only those partices which have an antiparticle partner are those that have mass? I believe that the higgs boson has mass and does not have an antiparticle partner. Are there others? Or is that a special case?

Please read this article:

https://en.wikipedia.org/wiki/Higgs_mechanism

in particular, masses of particles are discussed in these sections:
1.1 Structure of the Higgs field
1.2 The photon as the part that remains massless
1.3 Consequences for fermions
 
Or just check the Wikipedia pages of the different particles.
Feel free to open a new thread if you have questions that cannot be easily answered by a google/wikipedia search, but continuing this thread would be pointless.
