摘要：

The question of the resonance signal extraction from the invariant mass distribution of two particles is examined for the experimental situation of multiparticle events measured in a large acceptance detector. The different contributions to the distribution are calculated. Their magnitude is related to the particle pair combinatorics. The consequences for the resonance extraction methods based on event mixing are given. The situation is investigated in the framework of a simulation for relativistic heavy ion collisions. Finally, the formalism developed for one kind of resonance decaying in two different particles is generalized to other cases.
