Energy momentum of massless particles

Click For Summary
SUMMARY

The discussion centers on the energy momentum relation for massless particles, specifically the equation E = cp, which applies to these particles before electroweak symmetry breaking. Participants confirm that massless particles can indeed be described using this relationship. Furthermore, the conversation highlights that massless particles still exist today, reinforcing the relevance of this equation in contemporary physics.

Before electroweak symmetry breaking, there were massless particles. Can these massless particles be seen in terms of energy momentum relation ##E = ##c##p##?

There are still some massless particles today.

E=cp for massless particles, yes.
