sirios said:well, what I tried to ask was this: if there is a theory, other than string theory, that explains how an electric field of a quark or lepton is generated from photons? or how is the property of the electric charge defined, ie, positive or negative? since the theoretical models can not go beyond the quarks.
Thank you só muchbhobba said:You are confused about a number of things:
1. Everything is not made of photons
2. The basis of electric charge is not a definition but comes from what's called U(1) symmetry.
3. Unfortunately, right now, string theory hasn't quite worked out as its originators hoped - it was a very valuable development but has not really explained anything fundamental like symmetry I mention above, but is still in active development:

I think you need, in light of the above restate your query. But the following may help you:

String theory does not explain that.sirios said:Hi guys, I'm correcting the question because I think a lot of people did not understand what I asked, well, what I tried to ask was this: if there is a theory, besides string theory, that explains how an electric field of a quark or lepton are generated from photons? or how is defined the property of electric charge, ie, positive or negative? since the theoretical models can not go beyond the quarks.
Electromagnetic fields of fundamental particles are the force fields generated by charged particles, such as electrons and protons, that interact with each other through the exchange of photons.
Electromagnetic fields play a crucial role in understanding the behavior and interactions of fundamental particles. They help us explain phenomena such as the electromagnetic force, which is responsible for holding atoms and molecules together, and the emission and absorption of light.
Electromagnetic fields can be measured through experiments using specialized equipment, such as particle accelerators and detectors. They can also be studied through theoretical models and calculations based on fundamental laws of physics, such as Maxwell's equations.
Yes, electromagnetic fields can be manipulated and controlled in particle physics experiments. For example, in particle accelerators, scientists can control the strength and direction of electromagnetic fields to accelerate and steer particles.
Understanding electromagnetic fields of fundamental particles can help us gain a deeper understanding of the fundamental nature of matter and the universe. It also has practical applications in fields such as technology and medicine, where electromagnetic fields are used in devices like MRI machines and particle accelerators.
