摘要

We propose a method to estimate the probability of new physics discovery in future high energy physics experiments. Physics simulation gives both the average numbers <Nb> of background and <Ns> of signal events. We find that the proper definition of the significance for <Nb>, <Ns> >> 1 is S_{12} = sqrt(<Ns>+<Nb>) - sqrt(<Nb>) in comparison with often used significances S_1 = <Ns>/sqrt(<Nb>) and S_2 = <N_s>/sqrt(<Ns> + <Nb>). We propose a method for taking into account the systematical errors related to nonexact knowledge of background and signal cross sections. An account of such systematics is very essential in the search for supersymmetry at LHC. We also propose a method for estimation of exclusion limits on new physics in future experiments.
