Precise predictions for Higgs-masses in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) — •Peter Drechsel and Georg Weiglein — DESY, Notkestraße 85, 22607 Hamburg

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 at 1-loop order obtained by diagrammatic methods (the dominant 2-loop corrections will be implemented as a further step in the project). It will also provide some insights into the basic principles of the calculation, especially the renormalization of softly broken supersymmetric gauge theories.
