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.

Web2. The missing mass was compared with the values of pion masses, where the latter were chosen taking into account the charge of the mother particle and the presence of pions in the decay products. If the residual mass was found to be less than the pion mass, the number of possible L-L bonds was additionally determined. 3. WebApr 6, 2024 · The rest mass of the mesons lies between 250-100 mₑ .
