Weak electricity of the Nucleon in the Chiral Quark-Soliton Model — •Hyun-Chul Kim1, Maxim V. Polyakov2, and Klaus Goeke11Institute for Theoretical Physics II, Ruhr-University Bochum, D-44780 Bochum, Germany — 2Petersburg Nuclear Physics Institute, Gatchina, St. Petersburg 188350, Russia

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 mumd. We obtain for mumd=−5 MeV a value of gT/gA =−0.0043.
