摘要：

In view of the imminent start of the LHC experimental programme, we use the available indirect experimental and cosmological information to estimate the likely range of parameters of the constrained minimal supersymmetric extension of the Standard Model (CMSSM), using a Markov-chain Monte Carlo (MCMC) technique to sample the parameter space. The 95% confidence-level area in the (m0, m1/2) plane of the CMSSM lies largely within the region that could be explored with 1 fb(-1) of integrated luminosity at 14TeV, and much of the 68% confidence-level area lies within the region that could be explored with 50 pb(-1) of integrated luminosity at 10TeV. A same-sign dilepton signal could well be visible in most of the 68% confidence-level area with 1 fb(-1) of integrated luminosity at 14TeV. We discuss the sensitivities of the preferred ranges to variations in the most relevant indirect experimental and cosmological constraints and also to deviations from the universality of the supersymmetry-breaking contributions to the masses of the Higgs bosons.
