Abstract
Photon radiation induced by multiple parton rescattering andcorresponding parton energy loss in eA deeply inelastic scattering areinvestigated by using the generalized factorization of higher twistparton distributions beyond the helicity amplitude approximation. Itturns out that the behaviour of the nuclear size dependence of theparton energy loss is different in the photon and gluon radiation cases.The parton energy loss due to photon radiation depends linearly,instead of quadratically, on nuclear size due to gluon radiation.
