1. 1. Charged Higgs Boson Studies in the Channel pp→a1h±→4b+l+MET in the Next-to MSSM (NMSSM) with the ATLAS Experiment

   Master-uppsats, Högenergifysik

   Författare :Stephan Zimmer; [2010]
   Nyckelord :ATLAS; Charged Higgs; NMSSM; Beyond Standard Model; Supersymmetry; MSSM;

   Sammanfattning : Next-to-minimal super-symmetric extensions of the Standard Model (SM) predict the existence of several non-SM like Higgs bosons. The process pp→a1h±→4b+W involves the production and the decay of a spin-0 charged Higgs boson and a CP-odd Higgs boson a1 which can have a sizable cross section in the NMSSM. LÄS MER

3. 2. Charged Higgs Boson Studies in ttbar -Dilepton Events at the LHC

   L3-uppsats, Högenergifysik

   Författare :Stephan Zimmer; [2009]
   Nyckelord :Charged Higgs; Supersymmetry; ttbar; Dilepton; Spin Distribution;

   Sammanfattning : A generator-level study of dilepton ttbar events to search for light charged Higgs bosons at the LHC is presented with the aim of finding a new variable to discriminate between charged Higgs signals and Standard Model signatures. The spin effects in leptonic decays of H± and W bosons are studied and a new angular distribution is identified as a discriminating variable. LÄS MER
