Gravity and the Fermion Mass

Abstract

It is shown that gravity generates mass for the fermion. It does so by coupling directly with the spinor field. The coupling term is invariant with respect to the electroweak gauge group $U(1)\otimes SU(2{)}_L.$ It replaces the fermion mass term $m\bar{\psi }\psi$.
