| Sumario: | The production of W bosons decaying into a tau lepton and a neutrino with the tau lepton decaying semi-hadronically has been observed in LHC pp collisions at $\sqrt{s} = 7$~TeV with the CMS detector. The selection criteria provide a statistically significant signal
on the top of QCD multi-jet and electroweak
backgrounds. A data-driven method for the estimation
of the QCD multi-jet background has been employed. |
