Abstract

The possibility of searching for the effects of local spatial parity violation in strong interactions in the decay of a charged a0 meson into a charged pion and photon has been investigated. Using the Monte Carlo generator Pythia, the spectrum of invariant masses of π±γ pairs was studied, considering the decay channel a0± → π± + γ. An estimate was obtained for the minimum number of pp and Pb-Pb collision events for a significant level of the P-violating decay signal.
