CONSTRAINING THE RIGHT-HANDED INTERACTIONS FROM PION CONDENSATE MATTER

Abstract

We consider right-handed neutrino emission from charged and neutral pion condensate matter that could have been present in the supernova core associated with SN 1987 A. This is used to constrain the strength of right-handed interactions and we get an excluded range of values for the right-handed W boson and extra neutral Z' boson masses. For vanishing WL–WR mixing we obtain (1.3–1.8) MWL ≈≤ MWR ≤≈ (370–700) MWL and (1.3–1.8) MWL ≈≤ MN' ≤≈ 158MWL.
