Possible Interference Phenomena between Parity Doublets

Abstract

Possible interference phenomena between parity doublets are discussed. In particular, the decay particle distributions of ${\Sigma }^{\pm }$ and ${\Lambda }^0$ produced in $K^{-}+p$ capture and in ${\pi }^{-}+p$ collision are analyzed. These distributions may have interference terms with odd parity. Experimental detection of such terms would constitute an unambiguous proof of the existence of parity doublets. It is further pointed out that such interference terms have a rather interesting time dependence.
