SUSY II
- Linda Carpenter (Ohio State University)
We suggest simple ways of implementing Peccei-Quinn (PQ) symmetry to solve the strong CP problem in renormalizable SUSY SO(10) models with a minimal Yukawa sector. Realistic fermion mass generation requires that a second pair of Higgs doublets survive down to the PQ scale. We show how unification of gauge couplings can be achieved in this context. Higgsino mediated proton decay rate is...
Particle physics models with Peccei-Quinn (PQ) symmetry breaking as a consequence of supersymmetry (SUSY) breaking are attractive in that they solve the strong CP problem with a SUSY DFSZ-like axion, link the SUSY breaking and PQ breaking intermediate mass scales and can resolve the SUSY $\mu$ problem with a naturalness-required weak scale $\mu$ term whilst soft SUSY breaking terms inhabit the...
We report on an intriguing observation that the values of all the couplings in the standard model except those related to first two generations can be understood from the IR fixed point structure of renormalization group equations in the minimal supersymmetric model extended by one complete vectorlike family with the scale of new physics in a multi-TeV range.
Models of electroweak supersymmetry with vanishing scalar masses at some high scale is well motivated as it suppresses dangerous flavor violating contributions. Therefore, loop suppressed and log enhanced gaugino mediated contribution remains the only source of scalar masses. Consequently, right handed sleptons turn out to be the lightest supersymmetric particles which is cosmologically...
In this work, we initiate a study of continuum SUSY signatures at LHC. Since we have not seen any new physics at LHC yet, one naturally asks what if the new physics’s first sign does not comprise new resonances. Here, we try to demonstrate a scenario in the context of SUSY.
We propose that the $\gamma + {\not E}$ signal at the Belle-II detector will be a smoking gun for supersymmetry (SUSY) in the presence of a gauged $U(1)_{L_\mu - L_\tau}$ symmetry. A striking consequence of breaking the enhanced symmetry appearing in the limit of degenerate (s)leptons is the non-decoupling of the
radiative contribution of heavy charged sleptons to the $\gamma - Z^\prime$...
We analyze a model of flavored gauge mediation in which the electroweak Higgs and messenger doublets are embedded in multiplets of a discrete non-Abelian symmetry. In this model, the minimal Higgs-messenger sector consistent with the 125 GeV Higgs mass is comprised of two vectorlike pairs of messenger fields. This model allows for the achievement of phenomenologically viable superpartner...
This talk will present a SUSY bi-axion model of high-scale inflation, in which the axionic/inflationary structure originates from gauge symmetry in an extra dimension. We show that local SUSY, although necessarily Higgsed during inflation, can naturally survive down to the $\sim$ TeV scale in order to resolve the electroweak hierarchy problem. This model presents an interesting interplay of...
