Rest mass of pion

WebJun 13, 2024 · Resonances are produced according to the same emission function as direct pions, with their pole masses. The decay vertex of a given resonance is determined according to an exponential distribution whose width is the lifetime of the resonance in question (in its rest frame): ρ (τ d) ∝ e − Γ R τ d.
