Masses of the neutral Higgs bosons at one-loop level in the NMSSM

The Higgs sector of the Next-to Minimal Supersymmetric Extension of the Standard Model features five neutral Higgs bosons. Compared to the MSSM it is extended by one additional complex singlet field. In order to distinguish the Higgs sectors of the different models in the Higgs searches, it is important to have accurate phenomenological predictions available. We contribute to this effort by presenting the full one-loop calculation of the masses of the neutral Higgs bosons in the framework of the NMSSM. We employ a renormalization scheme that mixes on-shell and DR renormalization conditions, which originate from the Higgs sector, as well as from the neutralino and chargino sectors, and thereby provide a nontrivial cross-check.
