DOWNLOAD EBOOKZusammenfassung: This thesis describes the search for the neutral Higgs Bosons of the Minimal Supersymmetric Standard Model. The Higgs boson decay mode considered is the decay into tau leptons with one electron or muon and one hadronically decaying tau lepton in the final state. The p-p collision data analysed have been recorded in 2010 and 2011 with the ATLAS experiment at an centre-of-mass energy of 7 TeV and corresponds to an integrated luminosity of about 4.7/fb

DOWNLOAD EBOOKA 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.

DOWNLOAD EBOOKA search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of 8TeV collected with the ATLAS detector at the Large Hadron Collider. The samples used for this search were collected in 2012 and correspond to integrated luminosities in the range 19.5-20.3 fb-1. The MSSM Higgs bosons are searched for in the [tau] [tau] final state. No significant excess over the expected background is observed, and exclusion limits are derived for the production cross section times branching fraction of a scalar particle as a function of its mass. The results are also interpreted in the MSSM parameter space for various benchmark scenarios.

DOWNLOAD EBOOKThis thesis describes a search for the Higgs boson, a new particle predicted by a theory called the minimal supersymmetric extension to the standard model (MSSM). The standard model of particle physics, the MSSM, and Higgs boson phenomenology are introduced briefly. The search presented in this thesis uses a single final state configuration, in which the Higgs boson decays to two tau leptons, with one tau decaying to a muon and neutrinos, and the other decaying to pions and a single neutrino. Two new methods are introduced in this analysis, the Tau Neural Classifier tau identification algorithm, and the Secondary Vertex fit tau pair mass reconstruction method. Both methods are discussed in detail. The analysis uses the 2010 dataset from the Compact Muon Solenoid (CMS) experiment, which contains 36 pb−1 of integrated luminosity at a center of mass energy of 7 TeV. In total, 573 events are selected in the analysis. We fit the observed tau pair mass spectrum and measure the composition of the events. The result is compatible with the standard model expectation. No excess of signal events is observed, and we set an upper limit on the cross section times branching ratio of a Higgs boson. This limit is interpreted in the parameter space of the MSSM.

DOWNLOAD EBOOKWe report on a first search for production of the lightest neutral CP-even Higgs boson (h) in the next-to-minimal supersymmetric standard model, where h decays to a pair of neutral pseudoscalar Higgs bosons (a), using 4.2 fb−1 of data recorded with the D0 detector at Fermilab. The a bosons are required to either both decay to??− or one to?+?− and the other to?+?−. No significant signal is observed, and we set limits on its production as functions of M{sub a} and M{sub h}.

DOWNLOAD EBOOKA search for neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is performed, using events recorded by the CMS experiment at the LHC. The dataset corresponds to an integrated luminosity of 24.6 fb−1, with 4.9 fb−1 at 7 TeV and 19.7 fb−1 at 8 TeV. To enhance the sensitivity to neutral MSSM Higgs bosons, the search includes the case where the Higgs boson is produced in association with a b-quark jet. No excess is observed in the tau-lepton-pair invariant mass spectrum. Exclusion limits are presented in the MSSM parameter space for different benchmark scenarios, mhmax, mhmod+, mhmod-, light-stop, light-stau, [tau]-phobic, and low-mH. Upper limits on the cross section times branching fraction for gluon fusion and b-quark associated Higgs boson production are also given.

DOWNLOAD EBOOKA search for the neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM), produced in proton-proton collisions recorded by the ATLAS detector, is presented. The data correspond to an integrated luminosity of 20.3 fb−1, with a center of mass energy of 8 TeV. The search focuses on final states where the Higgs bosons decay into a [tau]+[tau]− pair, with one [tau] lepton decaying leptonically and the other hadronically. Two analyses are performed which separately target low-mass and high-mass Higgs bosons, with the former divided into two sub-channels based on the presence or absence of a b-jet in final state. No evidence of new Higgs bosons is found, and upper limits are set on the cross-section times branching ratio of such Higgs bosons, and on the MSSM parameters m [Alpha] and tan [Beta].
