Opis
Izvleček:	A search is reported for Higgs boson decay to μ<sup>+</sup>μ<sup>-</sup>using data with an integrated luminosity of 24.8fb<sup>-1</sup>collected with the ATLAS detector in ppcollisions at √s=7 and8TeVat the CERN Large Hadron Collider. The observed dimuon invariant mass distribution is consistent with the Standard Model background-only hypothesis in the 120-150GeV search range. For a Higgs boson with a mass of 125.5GeV, the observed (expected) upper limit at the 95% confidence level is 7.0 (7.2) times the Standard Model expectation. This corresponds to an upper limit on the branching ratio BR(H→μ<sup>+</sup>μ<sup>-</sup>)of 1.5 × 10<sup>-3</sup>.
