Most generic models of hidden sector supersymmetry breaking do not feature singlets, and gauginos obtain masses from anomaly mediated supersymmetry breaking. If one desires a natural model, then the dominant contribution to scalar masses should be of the same order, i.e. also from AMSB. However, pure AMSB models suffer from the tachyonic slepton problem. Moreover, there is a large splitting...

A dynamical Supersymmetry breaking model that realizes the phenomenology of Dirac gaugino masses is presented. The theory uses an s-confining Seiberg dual of SQCD to obtain a metastable ISS-like SUSY breaking vacuum. The SM gauge group is realized as a subgroup of the global flavor symmetry. The meson fields of the magnetic theory are partnered with gauginos,obtaining a Dirac mass at one loop....

If low energy supersymmetry is realized in nature, the apparent discovery of a Higgs boson with mass around 125GeV points to a supersymmetric mass spectrum in the TeV or multi-TeV range. Multi-TeV scalar masses are a necessary component of supersymmetric models with pure gravity mediation or in any model with strong moduli stabilization. Here, we show that full scalar mass universality remains...

I will talk about the consequences, for the LHC, of gauge and third family Yukawa coupling unification with a particular set of boundary conditions defined at the GUT scale, which we characterize as effective "mirage" mediation. We performed a global chi-squared analysis including the observables M_W, M_Z, G_F, alpha_em, alpha_s(M_Z), M_top, m_b(m_b), M_tau, BR(B -> X_s gamma), BR(B_s -> mu^+...

The discovery of Higgs boson at the Large Hadron Collider has a great impact on the minimal supersymmetric extension of the Standard Model (MSSM). In the context of the constrained MSSM (CMSSM) and its slight extension with non-universal masses for the MSSM Higgs doublets, sparticles with mass > 1 TeV are necessary to reproduce the observed Higgs boson mass around 125 GeV. On the other hand,...

We present a general formalism for analyzing supersymmetric models where the Higgs sector directly couples to the messengers of supersymmetry breaking. Such Higgs-messenger interactions are strongly motivated by the discovery of a Higgs boson near 125 GeV, but they also raise the specter of the mu/B_mu and A/m_H^2 problems. Using our formalism, we identify new avenues to solving these problems...

We present results from a Bayesian analysis of our non-minimal grand unified SUGRA model where the gluino drives the radiative electroweak symmetry breaking. The model naturally leads to a unique mass hierarchy and is shown to be exceptionally consistent with experimental constraints. The model simultaneously satisfied null results within B physics while creating a large contribution to the...

We begin the study of a class of string-motivated effective supergravity theories in light of current data from the CERN Large Hadron Collider (LHC). The case of heterotic string theory, in which the dilaton is stabilized via non-perturbative corrections to the Kahler metric, will be considered first. This model is highly constrained and therefore predictive. We find that much of the...
