Weak electricity of the Nucleon in the Chiral Quark-Soliton Model

Abstract

The induced pseudotensor constant (weak electricity) of the nucleon is calculated in the framework of the chiral quark soliton model. This quantity originates from the G-parity violation and hence is proportional to $m_u-m_d$. We obtain for $m_u-m_d=-5MeV$ a value of $g_T/g_A=-0.0038$.
