Search for the Standard Model Higgs boson produced in association with a vector boson and decaying into a tau pair in pp collisions at $\sqrt{s} =$ 8 TeV with the ATLAS detector

摘要: A search for the Standard Model Higgs boson produced in association with a vector boson with the decay H→ττis presented. The data correspond to 20.3 fb−1 of integrated luminosity from proton-proton collisions at s√=8TeV 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/σSM for mH=125GeV, is μ< 5.6 (3.7). The measured value of the signal strength is μ=2.3±1.6.
