Özet

By using the minimal extension of the standard model and considering the general relativistic effects near the surface of a static neutron star in the presence of quintessence elds, we drive analytical expressions for the cross-section and energy deposition rate of the process (e e ! W;Z; ! e e ). We have also obtained the ratio of energy deposition to total Newtonian energy deposition (Q : =Q : Newt). We have displayed that the contributions of the electron neutrino's charge radius are more effective than the dipole moment in this process. The obtained solutions indicate that the contribution of the electron neutrino charge radius changes the results approximately (1{5)% depending on the R M value of the star.
