I would like to know if the electric charge of a particle, like electron, has always a definite value, or on the contrary the Heisenberg uncertainty principle should be applied to this magnitude.
Or asking that in another way, what is the observable operator associated to the charge of a particle?
Has the U(1) symmetry something to do with all that?
Thanks in advance!
