 v1 === Definition === In general, the probability that an event is accepted depends on the characteristics of the measured event, and not on the process that produced it. The measured probability density %$\bar{P}(x,\alpha)$% can be related to the produced probability density %$P(x,\alpha)$%: %$\bar{P}(x,\alpha)=Acc(x) P(x,\alpha)$% where %$Acc(x)$% is the detector acceptance, which depends only on %$x$% In general, the probability that an event is accepted depends on the characteristics of the measured event, and not on the process that produced it.
