Radiative corrections to two-neutrino double-beta decay

Jordy de Vries, Emanuele Mereghetti, Saad el Morabit +1

We use heavy-nucleus effective field theory to compute radiative corrections to two-neutrino double-${\hat{I}}^2$ decay ($2\hat{I}½{\hat{I}}^2{\hat{I}}^2$). Our main result is the first derivation of a universal r…
