“…A p-value is given, which we demanded to be at least 0.05, corresponding to a non-exclusion at 95% CL. For the computation of the Higgs boson masses, the effective couplings, the decay widths and branching ratios of the SM and NMSSM Higgs bosons, the Fortran code NMSSMCALC [69] is used. Besides the masses with the newly implemented two-loop corrections, it provides the SM and NMSSM decay widths and branching ratios including the state-of-the-art higher order corrections.…”

Abstract:We provide the two-loop corrections to the Higgs boson masses of the CPviolating NMSSM in the Feynman diagrammatic approach with vanishing external momentum at O(α t α s ). The adopted renormalization scheme is a mixture between DR and on-shell conditions. Additionally, the renormalization of the top/stop sector is provided both for the DR and the on-shell scheme. The calculation is performed in the gaugeless limit. We find that the two-loop corrections compared to the one-loop corrections are of the order of 5-10%, depending on the top/stop renormalization scheme. The theoretical error on the Higgs boson masses is reduced due to the inclusion of these higher order corrections.

The NMSSM represents an elegant and well motivated description for the observed phenomenology in high energy physics. In this model a scalar singlet together with its superpartner is added to the Higgs sector of the Minimal Supersymmetric Standard Model (MSSM). In order to compare the NMSSM with experimental data at the same level of accuracy as the MSSM, precise predictions for Higgs-boson masses in the NMSSM are a necessity. This work will focus on the prediction for the Higgs masses in the NMSSM at one-and two-loop order obtained by Feynman diagrammatic methods. While the one-loop calculation is performed in the full NMSSM, the two-loop contributions to the Higgs-boson self-energies are approximated by their MSSM counterparts. It is shown that in this way the two-loop contributions are well approximated for a wide range of parameters. The results are exemplified for an example scenario genuine to the NMSSM.

“…Several other tools aiming at the calculation of radiative corrections to the NMSSM spectrum have been developed in the past few years, e.g. NMSSMCALC [31,32] or SoftSUSY [33,34]. The latter focuses on the CP-conserving NMSSM, while NMSSMCALC allows for CP-violation but specializes in corrections to the Higgs spectrum.…”

Supersymmetric extensions of the Standard Model open up the possibility for new types of CP-violation. We consider the case of the Next-to-Minimal Supersymmetric Standard Model where, beyond the phases from the soft lagrangian, CP-violation could enter the Higgs sector directly at tree-level through complex parameters in the superpotential. We develop a series of Fortran subroutines, cast within the public tool NMSSMTools and allowing for a phenomenological analysis of the CP-violating NMSSM. This new tool performs the computation of the masses and couplings of the various new physics states in this model: leading corrections to the sparticle masses are included; the precision for the Higgs masses and couplings reaches the full one-loop and leading two-loop order. The two-body Higgs and top decays are also attended. We use the public tools HiggsBounds and HiggsSignals to test the Higgs sector. Additional subroutines check the viability of the sparticle spectrum in view of LEP-limits and constrain the phases of the model via a confrontation to the experimentally measured Electric Dipole Moments. These tools will be made publicly available in the near future. In this paper, we detail the workings of our code and illustrate its use via a comparison with existing results. We also consider some consequences of CP-violation for the NMSSM Higgs sector.
