Observation of $W\rightarrow\tau\nu$ Production in pp Collisions at $\sqrt s = 7 $ TeV
The production of W bosons decaying into a tau lepton and a neutrino with the tau lepton decaying 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 elec...

| description | The production of W bosons decaying into a tau lepton and a neutrino
with the tau lepton decaying 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. |
