Abstract

We present the Bayesian naturalness prior to quantify electroweak fine tuning in the NMSSM. The naturalness prior arises automatically as an Occam razor in Bayesian model comparison quantifying the plausability of electroweak symmetry breaking within the model. The prior incorporates the most widely used fine tuning measures as special cases. In particular, it captures features the Barbieri-Ellis-Giudice, and the Electroweak Fine Tuning measures.We present the amount of Bayesian fine tuning over parameter space slices of the Constrained MSSM, the Constrained NMSSM, and an 11 parameter NMSSM scenario. According to the naturalness prior the constrained models are less tuned than other fine-tuning measures indicate.
