Precise predictions for Higgs-masses in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) — •Peter Drechsel1, Georg Weiglein1, Sven Heinemeyer2, and Leo Galeta2 — 1Deutsches Elektronen-Synchrotron (DESY), Hamburg, Germany — 2Instituto de Física de Cantabria, Edificio Juan Jordá, Santander, Spain
The NMSSM represents an elegant and well motivated alternative description for the observed phenomenology in high energy physics. In this theory a scalar singlet together with its superpartner is added to the Higgs-sector of the Minimal Supersymmetric Standard Model (MSSM). In order to allow significant testing of the NMSSM by experiments precise predictions for the parameters of the theory are a necessity.
The talk will focus on the prediction for the Higgs-masses in the NMSSM up to 2-loop order obtained by diagrammatic methods. The numerical impact of partial contributions will be discussed as well as the validity and scope of the presented results.
