With Bayesian statistics, we investigate the full parameter space of the constrained “next-to-minimal” supersymmetric standard model (CNMSSM) with naturalness priors, which were derived in a previous work. In the past, most Bayesian analyses of the CNMSSM ignored naturalness of the electroweak (EW) scale by making prejudicial assumptions for parameters defined at the EW scale. We test the CNMSSM against the CMSSM with Bayesian evidence, which, with naturalness priors, incorporates a penalty for… Expand

Testing Higgs boson scenarios in the phenomenological NMSSM
There could be another scalar in nature quasi-degenerate with the observed one ($$h_{125}$$h125). This is possible in models such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM). TheExpand
Bayesian naturalness, simplicity, and testability applied to the $B-L$ MSSM GUT using GPU Monte Carlo
The lack of decisive experimental results to settle fundamental questions in physics has led to increasing reliance upon intuitive criteria such as naturalness, simplicity, and testability. We argueExpand
Bayesian analysis and naturalness of (Next-to-)Minimal Supersymmetric Models
A bstractThe Higgs boson discovery stirred interest in next-to-minimal supersymmetric models, due to the apparent fine-tuning required to accommodate it in minimal theories. To assess theirExpand

A bstractThe new minimal supersymmetric standard model (nMSSM), a variant of the general next to minimal supersymmetric standard model (NMSSM) without Z3 symmetry, features a naturally light singlinoExpand
Combined collider constraints on neutralinos and charginos
Searches for supersymmetric electroweakinos have entered a crucial phase, as the integrated luminosity of the Large Hadron Collider is now high enough to compensate for their weak productionExpand
Naturalness of the relaxion mechanism
A bstractThe relaxion mechanism is a novel solution to the hierarchy problem. In this first statistical analysis of the relaxion mechanism, we quantify the relative plausibility of a QCD and aExpand
Naturalness made easy: two-loop naturalness bounds on minimal SM extensions
A bstractThe main result of this paper is a collection of conservative naturalness bounds on minimal extensions of the Standard Model by (vector-like) fermionic or scalar gauge multiplets. Within, weExpand
Anapole moment of the lightest neutralino in the cMSSM
Abstract We study the anapole moment of the lightest neutralino in the constrained Minimal Supersymmetric Standard Model (cMSSM). The electromagnetic anapole is the only allowed electromagnetic formExpand
Supernatural supersymmetry and its classic example: M-theory inspired NMSSM
We briefly review the super-natural supersymmetry (SUSY), which provides a most promising solution to the SUSY electroweak fine-tuning problem. In particular, we address its subtle issues as well.Expand
Electroweak baryogenesis in the ℤ3$$ {\mathbb{Z}}_3 $$-invariant NMSSM
A bstractWe calculate the baryon asymmetry of the Universe in the ℤ3$$ {\mathbb{Z}}_3 $$-invariant Next-to-Minimal Supersymmetric Standard Model where the interactions of the singlino provide theExpand
