    Search for Neutral Mssm Higgs Bosons Decaying To Μ+µ- in Pp Collisions at S=7 and 8 Tev
    (Elsevier Ltd., 2016) Karapınar, Güler; Karapınar, Güler; 01. Izmir Institute of Technology
    A search for neutral Higgs bosons predicted in the minimal supersymmetric standard model (MSSM) for μ+μ- decay channels is presented. The analysis uses data collected by the CMS experiment at the LHC in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, corresponding to integrated luminosities of 5.1 and 19.3 fb-1, respectively. The search is sensitive to Higgs bosons produced either through the gluon fusion process or in association with a bb quark pair. No statistically significant excess is observed in the μ+μ- mass spectrum. Results are interpreted in the framework of several benchmark scenarios, and the data are used to set an upper limit on the MSSM parameter tanβ as a function of the mass of the pseudoscalar A boson in the range from 115 to 300 GeV. Model independent upper limits are given for the product of the cross section and branching fraction for gluon fusion and b quark associated production at s=8 TeV. They are the most stringent limits obtained to date in this channel. © 2015 The Authors.

    Search for Neutral Mssm Higgs Bosons Decaying Into a Pair of Bottom Quarks
    (Springer Verlag, 2015) CMS Collaboration; Karapınar, Güler; 01. Izmir Institute of Technology
    A search for neutral Higgs bosons decaying into a bb¯$$ \mathrm{b}\overline{\mathrm{b}} $$ quark pair and produced in association with at least one additional b quark is presented. This signature is sensitive to the Higgs sector of the minimal supersymmetric standard model (MSSM) with large values of the parameter tan β. The analysis is based on data from proton-proton collisions at a center-of-mass energy of 8 TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.7 fb−1. The results are combined with a previous analysis based on 7 TeV data. No signal is observed. Stringent upper limits on the cross section times branching fraction are derived for Higgs bosons with masses up to 900 GeV, and the results are interpreted within different MSSM benchmark scenarios, mh max, mh mod +, mh mod −, light-stau and light-stop. Observed 95% confidence level upper limits on tan β, ranging from 14 to 50, are obtained in the mh mod + benchmark scenario.[Figure not available: see fulltext.] © 2015, The Author(s).
