82. The Scale-Invariant NMSSM and the 126 GeV Higgs Boson

Michael Schmidt

The recent LHC discovery of a Higgs-like resonance at 126 GeV suggests that the minimal supersymmetric standard model must be modified in order to preserve naturalness. A simple extension is to include a singlet superfield and consider the scale-invariant NMSSM, whose renormalizable superpotential contains no dimensionful parameters. This extension not only solves the \mu-problem, but can...

83. SO(10) meets LHC

In terms of physics results, 2012 has been an exciting year. In July 2012, the ATLAS and CMS collaborations have discovered a new particle that is consistent with the Standard Model Higgs boson. At the same time, the LHC has pushed the lower limits for supersymmetric particles to new heights, and this has contributed to the anxiety in the physics community that SUSY, if realized in nature, may...

84. Light Staus and Enhanced Higgs Diphoton Rate in SUSY SO(10) Yukawa Unification

In SUSY SO(10) GUT the top, bottom and tau Yukawa couplings unify at the GUT scale. It is shown that in a MSSM scenario restricted by top-bottom-tau Yukawa unification and the SO(10) gauge symmetry the low-energy SUSY spectrum may consist of the 125 GeV Higgs and light, strongly-mixed staus leading to enhanced Higgs diphoton rate.

85. Gauge Mediation beyond Minimal Flavor Violation

Lorenzo Calibbi

We discuss a minimal modification of Gauge Mediation in which the messenger sector couples directly to the MSSM matter fields. These couplings are controlled by the same dynamics that explain the flavor hierarchies, and therefore are parametrically as small as the Yukawas. This setup gives rise to an interesting SUSY spectrum that is calculable in terms of a single new parameter. Due to large...

86. Minimal SUSY SU(5) GUT in the high-scale SUSY scenario

Natsumi Nagata

22/05/2013, 16:20

We revisit the minimal supersymmetric SU(5) grand unified theory (SUSY SU(5) GUT) in the high-scale SUSY scenario. Although the model has been believed to be excluded due to the too short lifetime of proton, we have found that it is possible to evade the experimental constraints on the proton decay rate if the supersymmetric particles have masses much heavier than the electroweak scale. Since...

87. Supersymmetric quiver gauge theories: a phenomenological perspective

Andreas Goudelis

22/05/2013, 16:40

The recent LHC discovery of a Higgs-like particle that could be involved in electroweak symmetry breaking places strong bounds on the parameter space of supersymmetric models. In particular, it has been argued that minimal gauge mediated supersymmetry breaking scenarios seem to be at odds with a Higgs boson of ~126 GeV. Supersymmetric quiver gauge theories are an already well-established...

88. Little hierarchy problem for new physics just beyond the LHC

Marco Fabbrichesi

22/05/2013, 17:00

I discuss two possible extensions to the standard model in which an inert singlet scalar state that only interacts with the Higgs boson is added together with some fermions. In one model the fermions provide for a see-saw mechanism for the neutrino masses, in the other model for grand unification of the gauge couplings. Masses and interaction strengths are fixed by the requirement of...

89. Automatized generation of non-SUSY RGEs for a general gauge field theory

Florian Lyonnet

22/05/2013, 17:20

In light of the conspicuous absence of SUSY in the energy range explored by the LHC in 2012, non-supersymmetric BSM scenarios are becoming more and more attractive. One key ingredient in exploring such BSM physics are the renormalization group equations (RGEs) that are essential for extrapolating the theory to higher energy scales. Although the 2-loop RGEs for a general quantum field theory...
