129. Flavor symmetry based MSSM: Model building and phenomenology

Kaladi Babu (Oklahoma State University)

04/05/2015, 14:00

parallel talk

Flavor symmetries acting on the three chiral families can be consistently used to suppress SUSY flavor violation in gravity mediated SUSY breaking models. Models of this type will be presented, and the resulting MSSM phenomenology will be developed.

158. Radiative Breaking of the Minimal Supersymmetric Left-Right Model

Mr Nathan Papapietro (University of Alabama)

04/05/2015, 14:15

We propose a new variation to the SUSY Left-Right model (LRM) by extending the Minimal B-L model. Starting from energies of $\sqrt{s}>7$ TeV, we can describe an intermediate scale for Grand Unification along the Pati-Salam path from SO(10). Here the breaking of $SU(2)_L\times SU(2)_R\times U(1)_{B-L}\rightarrow SU(2)_L\times U(1)_Y$ is by a doublet rather than a triplet. Analyzing the RGE...

153. SUSY $\mu$ term Generation via Radiative Breaking of PQ Symmetry

Hasan Serce (University of Oklahoma)

parallel talk

The discovery of Higgs boson with mass $m_h=125.09\pm0.24$ GeV confirms the particle content of the standard model but carries some fine-tuning questions along with it. While supersymmetry (SUSY) solves the Big Hierarchy problem (or EW fine tuning) involving quadratic divergences, there is a growing Little Hierarchy problem typified by the increasing gap between the W,Z and h masses ($\sim100$...

65. R Parity Violation From Discrete R Symmetries

Volodymyr Takhistov (University of California at Irvine)

04/05/2015, 14:45

parallel talk

With LHC not observing superpartners, minimal supersymmetric versions of the Standard Model (SM) are very constrained. We consider supersymmetric extensions of the SM in which the usual R or matter parity gets replaced by another R or non–R discrete symmetry that explains the observed longevity of the nucleon and solves the µ problem of MSSM. Such R-parity violating scenarios may lead to...

94. Minimal Dirac gauginos without supersoftness

Prof. Stephen Martin (Northern Illinois University)

04/05/2015, 15:00

parallel talk

I propose a mechanism for obtaining Dirac gaugino masses from an F-term VEV, without the usual accompanying "supersoft" scalar interactions. The mu problem can be solved in these models in a novel way, which decouples the Higgsinos from naturalness arguments. I will also briefly describe the resulting superpartner mass spectrum and make some comments on LHC phenomenology.

160. Clues for Simplified Models from SUGRA Sparticle Hierarchies and LHC Data

Sujeet Akula (Northeastern University)

04/05/2015, 15:15

parallel talk

Sparticle mass hierarchies contain significant information regarding the origin and nature of supersymmetry breaking. The hierarchical patterns are severely constrained by electroweak symmetry breaking as well as by the astrophysical and particle physics data. They are further constrained by the Higgs boson mass measurement. The sparticle mass hierarchies can be used to generate simplified...

14. LHC constraints on Mini-Split anomaly and gauge mediation and prospects for a future 100 TeV pp collider

Mr Hugues Beauchesne (Carleton University)

04/05/2015, 15:30

parallel talk

Stringent experimental constraints have raised the lower limit on the masses of squarks to TeV levels, while compatibility with the mass of the Higgs boson provides an upper limit. This two-sided bound has lead to the emergence of Mini-Split theories where gauginos are not far removed from the electroweak scale while scalars are somewhat heavier. This small hierarchy modifies the spectrum of...

122. The 2015+ Phenomenology of Deflected Mirage Mediation

Todd Garon (UW-Madison)

04/05/2015, 15:45

parallel talk

We consider the phenomenology of deflected mirage mediation, a "mixed" supersymmetry breaking scenario motivated by string compactifications in light of results from LHC8, PLANCK, and LUX. In this scenario, there are additional gauge mediation contributions along with the standard gravity and anomaly mediation contributions of the KKLT-motivated mirage mediation scenarios, which drastically...
