Mixed Sneutrinos, Dark Matter and the LHC
Zoe Thomas, David Tucker-Smith, Neal Weiner
We study the phenomenology of supersymmetric models in which gauge-singlet scalars mix with the MSSM sneutrinos through weak-scale terms. After reviewing the constraints on mix…
Flavor in Supersymmetry with an Extended R-symmetry
Graham D. Kribs, Erich Poppitz, Neal Weiner
We propose a new solution to the supersymmetric flavor problem without flavor-blind mediation. Our proposal is to enforce a continuous or a suitably large discrete R-symmetry on we…
Sensitivity and Insensitivity of Galaxy Cluster Surveys to New Physics
Joshua Erlich, Brian Glover, Neal Weiner
We study the implications and limitations of galaxy cluster surveys for constraining models of particle physics and gravity beyond the Standard Model. Flux limited cluster counts p…
Natural Priors, CMSSM Fits and LHC Weather Forecasts
Ben C Allanach, Kyle Cranmer, Christopher G Lester +1
Previous LHC forecasts for the constrained minimal supersymmetric standard model (CMSSM), based on current astrophysical and laboratory measurements, have used priors that are flat…
Electroweak Radiative Corrections to Muon Capture
A. Czarnecki, W. J. Marciano, A. Sirlin
Electroweak radiative corrections to muon capture on nuclei are computed and found to be sizable. They enhance the capture rates for hydrogen and helium by 2.8% and 3.0% respective…
