Le C-Test comme outil d'évaluation en langue dans le cadre d'une enquête internationale : tentative de mise à l'épreuve

A search for supersymmetry is presented using a sample of events with b jets
and missing transverse momentum. The search uses a data sample of proton-proton
collisions at a centre-of-mass energy of 7 TeV, corresponding to an integrated
luminosity of 35 inverse picobarns, collected with the CMS detector. A total of
0.33 +0.43 -0.33 (stat.) +/- 0.13 (syst.) events is predicted, using control
samples in the data, to arise from standard model processes, and one event is
observed in the data. Upper limits are set at the 95% confidence level on the
cross sections of benchmark supersymmetric models.
