The quenching of the neutrino mean free path is evaluated to be about 12-58% for the values of μν=3×10−12μB and Rν=3.5×10−5MeV−1 compared with that obtained for the μν=0 and Rν=0. We find that the increase of the cross section relative to that without neutrino form factors results in the decrease of the neutrino mean free path when neutrino form factors and the in-medium modifications of the nucleon weak and electromagnetic form factors are simultaneously considered.

We analyze the neutrino scattering cross section and mean free path in cold nuclear matter. We use a relativistic mean-field model for the in-medium effective nucleon mass and quark-meson coupling model for nucleon form factors. Each contribution of the neutrino form factors to the neutrino mean free path is discussed.Ībstract = 'Effects of neutrino charge radius and magnetic moment constraints obtained from the astrophysical observations and reactor experiments, as well as in-medium modifications of the weak and electromagnetic nucleon form factors of the matter on the neutrino electroweak interaction with dense matter, are estimated.
