Non-Hermitian weak hadronic current and the ??? leptonic decay

Abstract

It is shown that an antihermitian contribution to the isotriplet of weak hadronic strangeness-conserving currents leads to a charge asymmetry. The existence of such currents with “wrong” G-parity is neither established nor refuted by existing experimental data. A deviation of Γ(Σ−→Λe−v)/Γ(Σ+→Λe+v) from the phase space ratio by more than ≈2 percent strongly suggests the presence of an antihermitian weak hadronic current, irrespective of time reversal invariance or CVC being valid or not.
