137. Electroweak symmetry breaking by a neutral sector: Dynamical relaxation of the little

We propose a new dynamical relaxation mechanism based on a singlet extension of the MSSM. In this scenario, a small enough soft mass of the MSSM singlet is responsible for the electroweak symmetry breaking and the Higgs VEV of order 100 GeV, whereas the effects of a large soft mass parameter of the Higgs boson, −m_{hu}^2 are dynamically compensated by an MSSM singlet field. The smallness of...

It is known that in the absence of a gauge singlet field, a specific class of supersymmetry (SUSY) breaking non-holomorphic (NH) terms can be soft breaking in nature so that they may be considered along with the Minimal Supersymmetric Standard Model (MSSM) and beyond. There have been studies related to these terms in minimal supergravity based models. Consideration of an F-type SUSY breaking...

139. A role of SUSY before/around Planck

Considering NLSUSY-structure of space-time just inspired by nonlinear representation of SUSY(NLSUSY) and performing the ordinary geometric arguments of Einstein general relativity(GR) principle, we obtain NLSUSY invariant Einstein-Hilbert-type general relativity action(nonlinear supersymmetric general relativity (NLSUSYGR)) equipped with the cosmological term of the robust SUSY breaking...

140. Bayesian Analysis and Naturalness in (Next-to-)Minimal SUSY Models

One of the key motivations for supersymmetric (SUSY) models is their ability to naturally stabilize the electroweak scale and so address the hierarchy problem. However, in the Minimal Supersymmetric Standard Model (MSSM) accommodating a 125 GeV Higgs boson appears to once again require a degree of fine-tuning. This has fueled interest in non-minimal SUSY models, such as the Next-to-MSSM...
