Hi all,
I'd like to know how the chiral symmetry protect the electron mass in the one-loop calculation of the electron self energy
and we finally get the mass radiative corrections as a logarithmic divergence.
It's known that the Dirac particle mass term : ## m \bar{\psi} \psi## could be written as ## m (\bar{\psi}_L \psi_R + \bar{\psi}_R \psi_L ) ##, so is there a simple explanation why the chiral symmetry keeps ## \Delta m \sim ln \Lambda \sim m ##, where ##\Lambda## the cutoff.
Bests,
