search for charged higgs Bosons produced via vector boson fusion and decaying into a pair of w and z Bosons using pp collisions at s 13 tev
Physical Review Letters, 2017Co-Authors: A M Sirunyan, A Tumasyan, W Adam, T Bergauer, M Dragicevic, J Ero, E Asilar, J Brandstetter, E Brondolin, Martin FlechlAbstract:A search for charged Higgs Bosons produced via vector boson fusion and decaying into W and Z Bosons using proton-proton collisions at root s = 13 TeV is presented. The data sample corresponds to an integrated luminosity of 15.2 fb(-1) collected with the CMS detector in 2015 and 2016. The event selection requires three leptons (electrons or muons), two jets with large pseudorapidity separation and high dijet mass, and missing transverse momentum. The observation agrees with the standard model prediction. Limits on the vector boson fusion production cross section times branching fraction for new charged physical states are reported as a function of mass from 200 to 2000 GeV and interpreted in the context of Higgs triplet models.

search for neutral higgs Bosons decaying to tau pairs in pp collisions at s 7 tev
Physics Letters B, 2012Co-Authors: S. Chatrchyan, V Khachatryan, A M Sirunyan, A Tumasyan, W Adam, T Bergauer, M Dragicevic, J Ero, C Fabjan, M FriedlAbstract:A search for neutral Higgs Bosons decaying to tau pairs at a center-of-mass energy of 7 TeV is performed using a dataset corresponding to an integrated luminosity of 4.6 fb^(−1) recorded by the CMS experiment at the LHC. The search is sensitive to both the standard model Higgs boson and to the neutral Higgs Bosons predicted by the minimal supersymmetric extension of the standard model (MSSM). No excess of events is observed in the tau-pair invariant-mass spectrum. For a standard model Higgs boson in the mass range of 110–145 GeV upper limits at 95% confidence level (CL) on the production cross section are determined. We exclude a Higgs boson with m_H=115 GeV with a production cross section 3.2 times of that predicted by the standard model. In the MSSM, upper limits on the neutral Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, m_A, sets stringent new bounds in the parameter space, excluding at 95% CL values of tan β as low as 7.1 at m_A=160 GeV in the m^(max)_h benchmark scenario.

search for neutral minimal supersymmetric standard model higgs Bosons decaying to tau pairs in pp collisions at s 7 tev
Physical Review Letters, 2011Co-Authors: S. Chatrchyan, V Khachatryan, A M Sirunyan, A Tumasyan, W Adam, T Bergauer, M Dragicevic, J Ero, C Fabjan, M FriedlAbstract:A search for neutral MSSM Higgs Bosons in pp collisions at the LHC at a center-of-mass energy of 7 TeV is presented. The results are based on a data sample corresponding to an integrated luminosity of 36 inverse picobarns recorded by the CMS experiment. The search uses decays of the Higgs Bosons to tau pairs. No excess is observed in the tau-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent new bounds in the MSSM parameter space.

neutral higgs boson masses of the mssm at the one loop level in an explicit cp violation scenario
Physical Review D, 2003Co-Authors: S K OhAbstract:The neutral Higgs sector of the minimal supersymmetric standard model in an explicit $\mathrm{CP}$ violation scenario is investigated at the one-loop level. Within the context of the effective potential formalism, the masses of the neutral Higgs Bosons are calculated at the one-loop level by taking into account the contributions of the following loops of ordinary particles and superpartners: the top quark, the scalar top quarks, the bottom quark, the scalar bottom quarks, the tau lepton, the scalar tau leptons, the W boson, the charged Higgs boson, the charginos, the Z boson, the scalar and pseudoscalar Higgs Bosons, and the neutralinos. Our calculation is an improvement in the sense that both the terms which are quartic in the electroweak coupling constants are taken into account, and the pseudoscalar Higgs loop contribution is explicitly included.
