| contents | Extending SUSY reach at the CERN Large Hadron Collider using b-tagging J. K. Mizukoshi Xerxes Tata P. G. Mercadante Física, Astronomía y Matemáticas LHC SUSY Jets Supergravity Supersymmetry We analyze the potential of the CERN Large Hadron Collider on the reach of the focus point (FP) regionin the mSUGRA parameter space. This region, consistent with WMAP results, is characterized by multi-TeVmasses for the superpartners of quarks and leptons and relatively light charginos and neutralinos. Moreover,since the LSP has a substantial higgsino component, it is expected that the gluino decays predominantly tothird generation quarks, producing a final state with multiple hard b jets. Analyzing events with 6ET +n jets +tagged b-jets, we show that the LHC reach can improve as much as 20% from current projections. Although weperformed the analysis specifically for the FP region, the b-tagging should be important to enhance the SUSYsignal in a variety of models where a relatively light gluino decays mostly to third generation quarks. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437413 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.37 |
