Radiative mass in QCD at high density

Abstract

We show that radiatively generated Majorana mass for antiquarks is same as the Cooper-pair gap. We then calculate the electromagnetic corrections to mass of particles in the color-flavor locking phase of QCD at high density. The mass spectrum forms multiplets under $SU(2{)}_V\times U(1{)}_V$. The charged pions and kaons get the electromagnetic mass which is proportional to the Cooper-pair gap.
