Is it possible to simulate in Geant4 electromagnetic properties of neutrinos such as the neutrino's electric charge, the neutrino's charge radius and the neutrino's magnetic moment (taking into account both the Standard Model as well as models or theories beyond the Standard Model of particle physics) ?
See examples/extended/exoticphysics/ for ways to define your own particles and processes.
Okay, thanks for your reply. It has been useful. So, in order to define neutrinos with the electromagnetic properties that I want, Would I have to do this writing code only in the Physics List class?. One more thing, in the PrimaryGeneratorAction class I don't have to specify any electromagnetic properties of neutrinos or do I?, I ask this because in the PrimaryGeneratorAction class of some of the examples in the Exotic Physics folder the definition of a particle is included, that's why I had this doubt.
Pick one of the examples, read the documentation, and look at what kinds of code (subclasses, which base classes, etc.) was written for that example. The forums are not a replacement for the documentation, nor are you going to find someone to write your code for you.
Ok, thanks for your reply and advices. I think I'll check out the ultra cold neutrons example.
