Higgs and $Z \rightarrow \tau^{+} \tau^{-}$ in CMS

The production of oppositely--charged tau lepton pairs is studied at $7$~\TeV center--of--mass energy using $36$~pb$^{-1}$ of proton-proton collision data collected by the CMS experiment in 2010. Events are selected in a combination of different final states resulting from hadronic and leptonic tau decays. The $Z \rightarrow \tau^{+} \tau^{-}$ cross--section is measured. The tau--pair kinematics is fully reconstructed using a likelihood technique. The mass spectrum observed in data is used to derive upper bounds on the production cross section times branching ratio to tau--pairs as a function of the Higgs boson mass in the Minimal Supersymmetric extension of the Standard Model (MSSM).
