Constraining the Right Handed Interactions from Pion Condensate Matter

Abstract

We consider right handed neutrino emission from charged and neutral pion condensate matter likely to be present in the supernova core associated with SN 1987 A. This is used to constrain the strength of right handed interaction and we get excluded range of values for the right handed $W$ boson and extra neutral $Z^{'}$ boson masses. For vanishing $W_{L} - W_{R}$ mixing we obtain $(1.3 - 1.8) M_{W_{L}} \approx\leq M_{W_{R}} \leq\approx 100 M_{W_{L}} and (1.3 - 1.8) M_{W_{L}} \approx\leq M_{N^{'}} \leq\approx 225 M_{W_{L}}$
