SUSY-Backgrounds to Searches of the Neutral Higgs Boson — •Bastian Feigl1, Heidi Rzehak2, and Dieter Zeppenfeld1 — 1TP, Karlsruhe Institute of Technology, Karlsruhe, Germany — 2CERN Theory Division, Geneva, Switzerland
Searches for neutral Higgs bosons may suffer from additional background contributions due to processes involving SUSY particles. Especially the decay products of gauginos and sleptons can mimic the leptonic signature l+l− + ¬ pT of a Higgs boson decaying into W+W− or, to a lesser extent τ+τ−.
We analyze those contributions within the Minimal Supersymmetric Standard Model (MSSM). We present differential cross sections and give an estimate of the impact on the Higgs boson searches in the gluon fusion and vector boson fusion channels.
