Destabilising Divergences in the NMSSM
The problem of destabilising divergences is discussed for singlet extensions of the MSSM. It is shown that models which possess either gauged-R symmetry or target space duality at the Planck scale are able to circumvent this problem whilst avoiding cosmological domain walls.
متن کاملZ-decays in the NMSSM
We study a subset of electroweak-precision observables consisting of MW , sin 2 θ eff, BR(Z → τ τ) and Γ(Z → ττ)/Γ(Z → ee)− 1 (characterizing leptonic Z-decays) in the context of the NMSSM. After a brief review of common MSSM-NMSSM effects (e.g. for Γ(Z → ττ)/Γ(Z → ee)− 1, which has been little discussed, even in the MSSM), specific NMSSM scenarios are studied, with the result that the NMSSM, c...
متن کاملDestabilising Conventions Using Temporary Interventions
Conventions are an important concept in multi-agent systems as they allow increased coordination amongst agents and hence a more efficient system. Encouraging and directing convention emergence has been the focus of much research, particularly through the use of fixed strategy agents. In this paper we apply temporary interventions using fixed strategy agents to destabilise an established conven...
متن کاملLight Neutralinos in the NMSSM
Next-to-Minimal Supersymmetric Standard Model neutralino dark matter candidates in the (1 − 15) GeV range are found with a Markov Chain Monte Carlo scanning code. A very light, singlet-like Higgs and/or CP-odd Higgs is needed in order to achieve such light masses. Light scalar Higgses can yield large direct detection cross sections, suitable for an account of the recent claims for signals. Neut...
متن کاملThe NMSSM implementation in WHIZARD
The Next-To-Minimal-Supersymmetric extension of the Standard Model (NMSSM) has been in the focus of extensive studies in the past two decades. In anticipation of the LHC era, the interest in automatized tools that can calculate collider signatures has grown. We present the implementation of the NMSSM into the event generator WHIZARD. In addition to a brief review of the implementation, we discu...
