Brandon Bryant (The Ohio State University)05/05/2014, 16:30We study Yukawa-unified SO(10) SUSY GUTs with two types of SO(10) boundary conditions: (i) universal gaugino masses and (ii) non-universal gaugino masses with "effective mirage" mediation. With these boundary conditions, we perform a global $\chi^2$ analysis to obtain the parameters consistent with 11 low energy observables, including the top, bottom, and tau masses. Both boundary conditions...Go to contribution page

Bin He (University of Delaware)05/05/2014, 16:45We study the implications of the inverse seesaw mechanism (ISS) on the sparticle spectrum in the Constrained Minimal Supersymmetric Standard Model (CMSSM) and Non-Universal Higgs Model (NUHM2). Employing the maximal value of the Dirac Yukawa coupling involving the up type Higgs doublet provides a 2-3 GeV enhancement of the lightest CP-even Higgs boson mass. This effect permits one to have...Go to contribution page

Dr Sogee Spinner (University of Pennsylvania)05/05/2014, 17:00An appealing framework for suppressing proton decay in supersymmetry is by considering models with gauged B-L symmetries. This is because R-parity is a subgroup of B-L. The minimal supersymmetric B-L model must violate B-L in such a way to spontaneous break R-parity, but keeps the proton safe. In this context, R-parity violation both generates neutrino masses and allows for the decay of the...Go to contribution page

Nathan Papapietro (University of Alabama)05/05/2014, 17:15We propose a simple gauged U(1)B−L extension of the minimal supersymmetric Stan- dard Model (MSSM), where R-parity is conserved as usual in the MSSM. The global B − L (baryon minus lepton number) symmetry in the MSSM is gauged and three MSSM gauge-singlet chiral multiplets with a unit B − L charge are introduced, ensuring the model free from gauge and gravi- tational anomalies. We assign...Go to contribution page

sonia el hedri (SLAC)05/05/2014, 17:30We place unitarity constraints on the SUSY breaking parameters in the Next-to-Minimal Supersymmetric Standard Model (NMSSM). To illustrate this analysis, we focus on a simple scenario where all of the SUSY breaking parameters originate from a common scale and the singlino and/or higgsino form the neutralino dark matter.Go to contribution page

Bryan Kaufman (Northeastern University)05/05/2014, 17:45We continue the study of a class of string-motivated effective supergravity theories in light of current data from the CERN Large Hadron Collider (LHC). In this installment we consider Type IIB string theory compactified on a Calabi-Yau orientifold in the presence of fluxes, in the manner originally formulated by Kachru, et al. We allow for a variety of potential uplift mechanisms and...Go to contribution page

Daniel Egana (R)05/05/2014, 18:00In the MSSM, a Higgs mass of 126[GeV] requires either heavy stops, leading to a little hierarchy problem, or maximal mixing. The latter alternative requieres models that generate sizable A-terms. On the other hand, a mechanism for SUSY breaking is required in the MSSM. Gauge mediation is one of the most popular mechanisms, since it is both very general and it does not introduce flavor...Go to contribution page

Todd Garon (UW-Madison)05/05/2014, 18:15We explore flavored gauge mediation models in which the electroweak Higgs fields and the $SU(2)$ doublet messengers of gauge mediation are embedded in multiplets of a non-Abelian discrete group (the Higgs-messenger group), as motivated by earlier work of Perez, Ramond, and Zhang. The Higgs-messenger group is part of a larger structure that includes a family symmetry group for the Standard...Go to contribution page
