Fixing the Pole in the Pyramid

Tom Banks, Jean-François Fortin, Scott Kathrein

We revisit the problem of the hidden sector Landau pole in the Pyramid Scheme. There is a fixed line in the plane of hidden sector gauge coupling and a Yukawa coupling between the…

Recent Work on Gravitational Waves From a Generic Standard Model-like Effective Higgs Potential

John Kehayias

I present recent work on gravitational waves (GWs) from a generic Standard Model-like effective potential for the electroweak phase transition. We derive a semi-analytic expression…

Cascade Events at IceCube+DeepCore as a Definitive Constraint on the Dark Matter Interpretation of the PAMELA and Fermi Anomalies

Sourav K. Mandal, Matthew R. Buckley, Katherine Freese +2

Dark matter decaying or annihilating into mu+mu- or tau+tau- has been proposed as an explanation for the e+e- anomalies reported by PAMELA and Fermi. Recent analyses show that IceC…

Semi-Analytic Calculation of the Gravitational Wave Signal From the Electroweak Phase Transition for General Quartic Scalar Effective Potentials

John Kehayias, Stefano Profumo

Upcoming gravitational wave (GW) detectors might detect a stochastic background of GWs potentially arising from many possible sources, including bubble collisions from a strongly f…

MSSM Baryogenesis and Electric Dipole Moments: An Update on the Phenomenology

Vincenzo Cirigliano, Yingchuan Li, Stefano Profumo +1

We explore the implications of electroweak baryogenesis for future searches for permanent electric dipole moments in the context of the minimal supersymmetric extension of the Stan…

All Possible Lightest Supersymmetric Particles in R-Parity Violating mSUGRA Models and their Signals at the LHC

H. K. Dreiner, S. Grab

We consider minimal supergravity (mSUGRA) models with an additional R-parity violating operator at the grand unification scale. This can change the supersymmetric spectrum leading…

Discrete R Symmetries and Low Energy Supersymmetry

Michael Dine, John Kehayias

If nature exhibits low energy supersymmetry, discrete (non-) R symmetries may well play an important role. In this paper, we explore such symmetries. We generalize gaugino con…

The impact of a strongly first-order phase transition on the abundance of thermal relics

Carroll Wainwright, Stefano Profumo

We study the impact of a strongly first-order electro-weak phase transition on the thermal relic abundance of particle species that could constitute the dark matter and that decoup…

Note on the pseudo-Nambu-Goldstone Boson of Meta-stable SUSY Violation

Tom Banks, Howard E. Haber

Many models of meta-stable supersymmetry (SUSY) breaking lead to a very light scalar pseudo-Nambu Goldstone boson (PNGB), P, associated with spontaneous breakdown of a baryon numbe…

Flavor Physics in the Quark Sector

M. Antonelli, D. M. Asner, D. Bauer +137

One of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor and measurements and theoretical interpretations of their res…

Can we discover dual-component thermal WIMP dark matter?

Stefano Profumo, Kris Sigurdson, Lorenzo Ubaldi

We address the question of whether the upcoming generation of dark matter search experiments and colliders will be able to discover if the dark matter in the Universe has two compo…

Generalized CP symmetries and special regions of parameter space in the two-Higgs-doublet model

P. M. Ferreira, Howard E. Haber, Joao P. Silva

We consider the impact of imposing generalized CP symmetries on the Higgs sector of the two-Higgs-doublet model, and identify three classes of symmetries. Two of these classes cons…

A Pyramid Scheme for Particle Physics

Tom Banks, Jean-François Fortin

We introduce a new model, the Pyramid Scheme, of direct mediation of SUSY breaking, which is compatible with the idea of Cosmological SUSY Breaking (CSB). It uses the trinification…
