Search for the Standard Model Higgs boson produced in the decay channel H$\rightarrow$ZZ$\rightarrow$2$l$2$\tau$ with CMS detector at $\sqrt s =$ 7 TeV

Search for the standard model Higgs boson in the decay mode $H\rightarrow ZZ\rightarrow2l2\tau$, where $l = \mu, e$ is presented based on CMS data corresponding to an integrated luminosity of 1.1 fb$^{-1}$ at $\sqrt s =$ 7 TeV. No evidence is found for a significant deviation from standard model expectations anywhere in the ZZ mass range considered in this analysis. An upper limit at 95$\%$ C.L. is placed on the product of the cross-section and decay branching ratio for the Higgs boson decaying with standard model like couplings, which excludes cross-sections of about ten times the expected value for Higgs boson masses in the range $200 < m\mathrm{_H} < 400$ GeV/c$^2$.
