Study of MSSM Higgs boson observalibility at CMS in four b jet final state — •Philippe Gras¹, Volker Drollinger², Thomas Müller¹, Günter Quast¹, and Christian Weiser¹ — ¹Institute für Experimentelle Kernphysik, Universität Karlsruhe (TH) — ²University of New Mexico, USA

In the Minimal Supersymetric Model (MSSM), the Higgs boson to b quark coupling is enhanced by the Higgs doublet vacuum expectation value ratio, tanβ. In the high tanβ region, b quark fusion is then the dominant Higgs production process. We have studied the observability of MSSM Higgs boson by looking for final states with four b-jets: two jets from the Higgs decay associated with two jets from the Higgs production process. This study has been done with a fast simulation of the CMS detector and a b-tagging procedure based on track impact parameters.
