Chiral corrections to the $SU(2)\times SU(2)$ Gell-Mann-Oakes-Renner relation

J. Bordes, C. A. Dominguez, P. Moodley +2

The next to leading order chiral corrections to the $SU(2)\times SU(2)$ Gell-Mann-Oakes-Renner (GMOR) relation are obtained using the pseudoscalar correlator to five-loop order in…
