Perturbative Unitarity Constraints on Gauge Portals
Sonia El Hedri, William Shepherd, Devin G. E. Walker
Dark matter that was once in thermal equilibrium with the Standard Model is generally prohibited from obtaining all of its mass from the electroweak phase transition. This implies…
Impact of LSP Character on Slepton Reach at the LHC
Jonathan Eckel, Michael J. Ramsey-Musolf, William Shepherd +1
Searches for supersymmetry at the Large Hadron Collider (LHC) have significantly constrained the parameter space associated with colored superpartners, whereas the constraints on c…
Searching for Dark Matter at Hadron Colliders
Andrew Askew, Sushil Chauhan, Bjorn Penning +2
Theoretical and experimental techniques employed in dedicated searches for dark matter at hadron colliders are reviewed. Bounds from the 7 and 8 TeV proton-proton collisions at the…
Tagging Boosted Ws with Wavelets
Vikram Rentala, William Shepherd, Tim M. P. Tait
We present a new technique for distinguishing the hadronic decays of boosted heavy particles from QCD backgrounds based on wavelet transforms. As an initial exploration, we illustr…
The Effective Hooperon
Alexandre Alves, Stefano Profumo, Farinaldo S. Queiroz +1
We explore the possibility of explaining a gamma-ray excess in the Galactic Center, originally pointed out by Hooper, collaborators, and other groups, in an effective field theory…
New Physics Contributions to the Muon Anomalous Magnetic Moment: A Numerical Code
Farinaldo S. Queiroz, William Shepherd
We consider the contributions of individual new particles to the anomalous magnetic moment of the muon, utilizing the generic framework of simplified models. We also present analyt…
