One-loop renormalisation of the NMSSM in SloopS 2: the Higgs sector

Understand

We present a full one-loop renormalisation of the Higgs sector of the Next-to-Minimal- Supersymmetric-Standard-Model (NMSSM) and its implementation within SloopS, a code for the automated computations of one-loop processes in theories beyond the Stan- dard Model.

• The present work is the sequel to the study we performed on the renor- malisation of the sectors of the NMSSM comprising neutralinos, charginos and sfermions thereby completing the full one-loop renormalisation of the NMSSM.
• We have investi- gated several renormalisation schemes based on alternative choices (on-shell or DR) of the physical parameters.
• Special attention is paid to the issue of the mixing between physical fields.
