Search for MSSM neutral Higgs bosons decaying to a muon pair in the mass range up to 130 GeV

Results are presented on the discovery potential for MSSM neutral Higgs bosons in a region of large anb, between 15 and 50, and mass between ~ 95 and 130 GeV, in the framework of the ATLAS experiment at the Large Hadron Collider (LHC), for a centre-of-mass energy root (s) = 14 TeV. The h/A bosons, s...

Sumario:Results are presented on the discovery potential for MSSM neutral Higgs bosons in a region of large anb, between 15 and 50, and mass between ~ 95 and 130 GeV, in the framework of the ATLAS experiment at the Large Hadron Collider (LHC), for a centre-of-mass energy root (s) = 14 TeV. The h/A bosons, supposed to be very close in mass in this parameter region, are studied in the channel h/A -> mumu accompanied by two b-jets. For completeness, a possible contribution of the H boson is studied in the same tan b, mA region. Use is made of an experimental method to control the most copious background, bbZ -> mumu accompanied by two b-jets. The region studied is not fully covered by the present data either from LEP or from Tevatron. These results override the ones from the preliminary study.
