One-loop renormalisation of the NMSSM in SloopS : 1. the neutralino-chargino and sfermion sectors

Understand

We have completed the one-loop renormalisation of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) allowing for and comparing between different renormalisation schemes.

• A special attention is paid to on-shell schemes.
• We study a variety of these schemes based on alternative choices of the physical input parameters.
• In this paper we present our approach to the renormalisation of the NMSSM and report on our results for the neutralino-chargino and sfermion sectors.
