Analysis of the NMSSM Higgs Boson Masses at One-Loop Level

Understand

For a reliable prediction of the NMSSM Higgs boson signatures at present and future high-energy colliders and a proper distinction of the NMSSM and MSSM Higgs sector the precise knowledge of the Higgs boson masses including higher-order corrections is indispensable.

• In this paper, the one-loop corrections to the neutral NMSSM Higgs boson masses and mixings are calculated in three different renormalisation schemes.
• In addition to the $\bar{DR}$ renormalisation scheme, existing in the literature, two other schemes are adopted.
• Furthermore, the dependence on the value of the top quark mass is investigated.
