Contribution

It provides a detailed one-loop level spectrum calculation for the NMSSM with a specific mSUGRA variant, comparing results with existing literature.

Findings

Computed the electroweak spectrum at one-loop level

Compared results with previous studies

Discussed implications for relic density calculations

Abstract

We present the electroweak spectrum for the Next-to-Minimal Supersymmetric Standard Model at the one-loop level, e.g.\ the masses of Higgs bosons, sleptons, charginos and neutralinos. For the numerical evaluation we present a mSUGRA variant with non-universal Higgs mass parameters squared and we compare our results with existing ones in the literature. Moreover, we briefly discuss the implications of our results for the calculation of the relic density.
