Abstract
We explore the model-building and phenomenology of flavored gauge mediation models of supersymmetry breaking in which the electroweak Higgs doublets and the SU(2) messenger doublets are connected by a discrete non-Abelian symmetry. The embedding of the Higgs and messenger fields into representations of this non-Abelian Higgs-messenger symmetry results in specific relations between the Standard Model Yukawa couplings and the messenger-matter Yukawa interactions. Taking the concrete example of an S(3) Higgs-messenger symmetry, we demonstrate that while the minimal implementation of this scenario suffers from a severe mu/B_mu problem that is well-known from ordinary gauge mediation, expanding the Higgs-messenger field content allows for the possibility that mu and B_mu can be separately tuned, allowing for the possibility of phenomenologically viable models of the soft supersymmetry breaking terms. We construct toy examples of this type that are consistent with the observed 125 GeV Higgs boson mass.
Highlights
The theoretical paradigm of TeV-scale supersymmetry (SUSY) continues to be one of the best-motivated candidates for new physics that can be probed extensively at the LHC
Supersymmetric extensions of the Standard Model (SM) such as the minimal supersymmetric Standard Model (MSSM) have already been subjected to stringent tests at the LHC, both from direct constraints such as the nonobservation of superpartners to date, with limits on colored superpartners that reach well into the TeV region, and constraints from the 2012 discovery [3,4] of a new scalar particle that is compatible with the SM Higgs boson
While the Higgs mass mh ≈ 125 GeV is within the allowed range of supersymmetric models, its relatively high value requires either (i) large stop mixing or very heavy stops in the MSSM or (ii) extended Higgs sectors
Summary
The theoretical paradigm of TeV-scale supersymmetry (SUSY) continues to be one of the best-motivated candidates for new physics that can be probed extensively at the LHC (see, f, Refs. [1,2] for reviews).

The data have placed severe limits on the viable regions of the vast (more than 100dimensional) parameter space of the MSSM, largely ruling out many minimal scenarios for the soft supersymmetrybreaking parameters
