【 摘 要 】

The search of neutral Higgs boson in two different decay channels, a pair of τ leptons and a pair of b-quarks, is presented. The search is performed in the context of the Minimal Supersymmetric Standard Model (MSSM), using data collected by the CMS experiment at the LHC during 2011-12 at a center-of-mass energy of 7-8 TeV. In the τ decay four independent pair final states, where one or both τs decay leptonically, are studied. In the b channel we look for final states with two high energetic jets plus a third jet, exploiting the production in association with b-quarks to enhance the signal purity in the selections of events. A description of the analyses strategies adopted for the two channels is provided. The results are presented and interpreted in the scenario of the MSSM framework.
