Dark energy from the string axiverse
Marc Kamionkowski, Josef Pradler, Devin G. E. Walker
String theories suggest the existence of a plethora of axion-like fields with masses spread over a huge number of decades. Here we show that these ideas lend themselves to a model…
Deconstructed Transverse Mass Variables
Ahmed Ismail, Reinhard Schwienhorst, Joseph S. Virzi +1
Traditional searches for R-parity conserving natural supersymmetry (SUSY) require large transverse mass and missing energy cuts to separate the signal from large backgrounds. SUSY…
Single Top Production as a Probe of Heavy Resonances
Elizabeth Drueke, Joseph Nutter, Reinhard Schwienhorst +3
The single top quark final state provides sensitivity to new heavy resonances produced in proton-proton collisions at the Large Hadron Collider. Particularly, the single top plus q…
Perturbative Unitarity Constraints on a Supersymmetric Higgs Portal
Kassahun Betre, Sonia El Hedri, Devin G. E. Walker
We place perturbative unitarity constraints on both the dimensionful and dimensionless couplings in the Next-to-Minimal Supersymmetric Standard Model Higgs Sector. These constraint…
Les Houches 2011: Physics at TeV Colliders New Physics Working Group Report
G. Brooijmans, B. Gripaios, F. Moortgat +141
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our report includes new agreem…
Dark Baryogenesis
Devin G. E. Walker
We first suggested a scenario in which a generic, dark chiral gauge group undergoes a first order phase transition in order to generate the observed baryon asymmetry in the univers…
