Abstract
Renormalization in quantum statistics in the presence of a charge asso ciated to a spontaneously broken symmetry is discussed for the scalar field model, In contrast with the case of non-broken symmetry, the ren ormalization mass counter term delta m(2) depends on the chemical pote ntial, We argue that this is connected to the ill-defined character of the charge operator,
