Search for the standard model Higgs boson produced in association with a vector boson and decaying into a tau pair in pp collisions at √s =8 TeV with the ATLAS detector

A search for the standard model Higgs boson produced in association with a vector boson with the decay H→ττ is presented. The data correspond to 20.3 fb −1 of integrated luminosity from proton-proton collisions at s √ =8 TeV recorded by the ATLAS experiment at the LHC during 2012. The data agree with the background expectation, and 95% confidence-level upper limits are placed on the cross section of this process. The observed (expected) limit, expressed in terms of the signal strength μ=σ/σ SM for m H =125 GeV, is μ
