Abstract	Particle identification, PID, is of crucial importance in most experiments. The requirement can range from positive π/K identification in B-physics channels like B\(^0_{\mathrm {s}}\rightarrow \)D\(^\mp _{\mathrm {s}}\)K± against a background from B\(^0_{\mathrm {s}}\rightarrow \)D\(^-_{\mathrm {s}}\pi ^+\) which is ∼15 times more abundant, to e/π separation at the level of ∼ 10−2 for momenta > 1 GeV/c in order to effectively suppress a combinatorial background in channels like leptonic decays of heavy vector resonances.
