Charged particles mass before symmetry breaking

In summary, before the symmetry breaking, electrically charged particles could be massless due to the existence of the Higgs field and the Higgs mechanism. This field also explains why other fundamental constituents of matter have mass. The electric field for massless QED is also different, with a logarithmic decrease in electric charge at long distances due to the creation of virtual particle-antiparticle pairs. This makes it easier to add more particles and screen the charge.

How could electrically charged particles be massless before the symmetry breaking? Wouldn't the energy stored in the electric field contribute to particles mass?

I didn't know there were any electrically charged massless particles.
It is interesting to contemplate an electric charge moving through space at light speed.
I guess it would be able to gain or loose energy on the fly.

Is the following relevant to the OP question?

From https://en.wikipedia.org/wiki/Higgs_boson#Higgs_field
According to the Standard Model, a field of the necessary kind (the Higgs field) exists throughout space and breaks certain symmetry laws of the electroweak interaction. Via the Higgs mechanism, this field causes the gauge bosons of the weak force to be massive at all temperatures below an extreme high value. When the weak force bosons acquire mass, this affects their range, which becomes very small. Furthermore, it was later realized that the same field would also explain, in a different way, why other fundamental constituents of matter (including electrons and quarks) have mass.​

The electric field for massless QED is very different from what you're used to. Specifically, the electric charge will go to zero logarithmically at long distances, so you won't have long-range Coulomb forces. The heuristic behind this is that it becomes "cheap" to create virtual massless particle-antiparticle pairs which screen any charge. Then it takes arbitrarily little energy to add another particle-antiparticle pair.

What are charged particles?

Charged particles are subatomic particles that have an electric charge, either positive or negative. Examples of charged particles include protons, electrons, and ions.

What is mass?

Mass is a fundamental property of matter that measures the amount of matter in an object. It is a measure of an object's resistance to acceleration when a force is applied.

What is symmetry breaking?

Symmetry breaking is a concept in physics where a system loses its symmetry due to external influences or interactions. In the context of charged particles, it refers to the breaking of symmetry between particles and their antiparticles.

What is the mass of charged particles before symmetry breaking?

The mass of charged particles before symmetry breaking is not well-defined and can vary depending on the specific particle. However, in particle physics, it is generally accepted that charged particles have zero mass before symmetry breaking occurs.

How does symmetry breaking affect the mass of charged particles?

Symmetry breaking can result in the creation of new particles and interactions, which can lead to the acquisition of mass for previously massless particles. This is known as the Higgs mechanism and is a crucial component of the Standard Model of particle physics.
