The correction for the trial factor or look-elsewhere effect is performed using pseudo-experiments that are generated with pseudo-data pulled from the SM background. For each pseudo-experiment, the most interesting region is calculated. Using an ensemble of such pseudo-experiments, the fraction of pseudo-experiments with a smaller Poisson probability for the most interesting region than that observed in data for a particular final state is evaluated. The value of is expected to be small for the case where there is a significant deviation observed in data possibly coming from a signal of new physics. Otherwise, it is expected to be a random number pulled from a uniform distribution in the unit interval. This process is done in each of the final states. The minimum of these values is denoted and the most interesting region in the final state with smallest is denoted .
