Search for neutral MSSM Higgs bosons decaying to tau(+)tau(-) pairs in proton-proton collisions at root s=7 TeV with the ATLAS detector
2011
Abstract
A search for neutral Higgs bosons decaying to pairs of tau leptons with the ATLAS detector at the LHC is presented. The analysis is based on proton-proton collisions at a center-of-mass energy of 7 TeV, recorded in 2010 and corresponding to an integrated luminosity of 36 pb^(-1).
After signal selection, 276 events are observed in this data sample. The observed number of events is consistent with the total expected background of 269 +/- 36 events.
Exclusion limits at the 95% confidence level are derived for the production cross section of a generic Higgs boson as a function of the Higgs boson mass and for A/H/h production in the Minimal Supersymmetric Standard Model (MSSM) as a function of the parameters m(A) and tan(beta).
