Аннотация

Accounting for the effects of local parity nonconservation in a strongly interacting medium is implemented within the framework of the Monte Carlo model. Predictions are obtained for the distributions of the invariant masses of di-muons and di-electrons from the decays of light vector mesons in Pb-Pb collisions at the LHC energy, taking into account the resolution of the detecting systems. The influence of fluctuations of the axial chemical potential is estimated.

5. Fig. 4. Effect of axial chemical potential fluctuations on the splitting of the spectral functions of ρ- and ω-mesons in the spectrum of invariant masses of di-muons (a, c) and di-electrons (b, d): 0.05 GeV < μ5 < 0.15 GeV (σμ ≈ 30%) (a, b), 0 GeV < μ5 < 0.2 GeV (σμ ≈ 60%) (c, d). The resolving power of the ALICE experiment under Run 3 conditions is taken into account.
