The Higgs Sector of the (Complex) NMSSM - Higher Order Corrections and Phenomenological Discussions

We study the Higgs sector of the Next-to-Minimal Supersymmetric Standard Model. With seven physical Higgs bosons the NMSSM offers plenty of phenomenologically interesting possibilities. Especially in light of the recent discovery of a scalar resonance at 125~GeV at the LHC a discussion of these is highly relevant. However, in order to draw meaningful conclusions regarding the true nature of the Higgs sector the availability of higher order corrections to parameters and observables is essential.
