Electrons are usually considered to be point-like particles but are there any
theories that say they have a non-zero radius?

The current understanding is that electrons are considered to be point-like particles, meaning they have no measurable size or volume.
The size of electrons is important to study because it can provide insight into the fundamental nature of matter and the behavior of particles at a subatomic level. It also has implications in fields such as quantum mechanics and particle physics.
Scientists use various methods, such as scattering experiments and quantum electrodynamics calculations, to try to measure the size of electrons. However, these methods have not been able to definitively determine whether electrons have a non-zero radius or not.
Some experiments, such as the Lamb shift and the anomalous magnetic moment of the electron, have shown small deviations from the point-like nature of electrons, which could indicate a non-zero radius. However, these results are not conclusive and more research is needed.
The debate over the size of electrons is a fundamental question in physics and has implications for our understanding of the nature of matter and the behavior of particles at a subatomic level. It also has implications for theories such as the Standard Model and can potentially lead to new discoveries and advancements in the field of physics.
