I am just wondering in pair production, what is the physics that determine the mass of the electrons? Why can't the electron get more mass than the positron or the other way round?

Khashishi said:The mass of the electron is something we measure from experiment. I don't believe there is any good theory for predicting the mass. We observe in bubble chambers and the like that the positron charge to mass ratio is the same as the electron charge to mass ratio. It's possible that there is some small difference in masses, but there's no compelling reason to believe so.
The mass of an electron is approximately 9.11 x 10^-31 kilograms.
An electron has mass because it is a fundamental particle and is believed to be an indivisible unit of matter. The mass of an electron is a fundamental property of the particle, similar to its charge and spin.
The mass of an electron is guaranteed by the Higgs field, which is a fundamental force in the universe that gives particles their mass. The Higgs field interacts with particles, such as electrons, through the Higgs boson, which gives them their mass.
The Higgs field is present throughout the universe and particles, such as electrons, interact with it by moving through it. As particles move through the Higgs field, they gain mass through the Higgs mechanism, which is a process of generating particle mass through interactions with the Higgs field.
The mass of an electron is a constant and does not change. However, its energy can change, which can affect its observed mass through Einstein's famous equation, E=mc^2.
