SUSY-Backgrounds to Searches of a Neutral Higgs Boson via Vector Boson Fusion — •Bastian Feigl1, Heidi Rzehak2, and Dieter Zeppenfeld1 — 1IThP, Karlsruhe Institute of Technology, 76128 Karlsruhe, Germany — 2Physikalisches Institut, Uni Freiburg, 79104 Freiburg, Germany
Within SUSY models, additional backgrounds to Higgs boson searches arise from the production and subsequent decay of superpartners.
We analyze possible SUSY backgrounds for Higgs Boson production in Vector Boson Fusion in the Minimal Supersymmetric Standard Model (MSSM). As signal we consider the leptonic final states h → τ+ τ− → l+l− + /pT and h → W+W− → l+l− + /pT.
Relevant processes that can have a significant impact for the chosen modified SPS1a scenario are the production of χ1+χ1− + jj(j) and χ20 χ10 + jj(j). After the Chargino and Neutralino-2 decay, these processes contribute to the l+l− jj(j) + /pT signature.
We present differential cross sections within a leading order analysis and the impact of Higgs mass reconstruction on the SUSY background.
