The Possibility of Finding the P Symmetry Breaking Decay of the Charged a0 Meson

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 was investigated. Using the Pythia Monte Carlo generator, the spectrum of invariant masses of π^±γ pairs was studied, taking into account the decay channel \(a_{0}^{ \pm }\) → π^± + γ. An estimate was made of the minimum number of pp and Pb–Pb collision events at a significant level of the P-violating decay signal.
