Searching for Direct Stop Production in Hadronic Top Data at the LHC
David E. Kaplan, Keith Rehermann, Daniel Stolarski
We argue that evidence can be uncovered for stops between 300-600 GeV in 5 fb^-1 of 7 TeV proton-proton collisions if they decay into top quarks and light neutral particles. We als…
Visible Supersymmetry Breaking and an Invisible Higgs
Daniele Bertolini, Keith Rehermann, Jesse Thaler
If there are multiple hidden sectors which independently break supersymmetry, then the spectrum will contain multiple goldstini. In this paper, we explore the possibility that the…
Weak Scale Leptogenesis, R-symmetry, and a Displaced Higgs
Keith Rehermann, Christopher M. Wells
We present a supersymmetric model of leptogenesis in which the right-handed neutrinos have weak scale masses and O(10-2-10-3) yukawa couplings. The model employs an R-symmetry at t…
Simplified Models for LHC New Physics Searches
Daniele Alves, Nima Arkani-Hamed, Sanjay Arora +92
This document proposes a collection of simplified models relevant to the design of new-physics searches at the LHC and the characterization of their results. Both ATLAS and CMS hav…
Dark Atoms: Asymmetry and Direct Detection
David E. Kaplan, Gordan Z. Krnjaic, Keith R. Rehermann +1
We present a simple UV completion of Atomic Dark Matter (aDM) in which heavy right-handed neutrinos decay to induce both dark and lepton number densities. This model addresses seve…
Efficient Identification of Boosted Semileptonic Top Quarks at the LHC
Keith Rehermann, Brock Tweedie
Top quarks produced in multi-TeV processes will have large Lorentz boosts, and their decay products will be highly collimated. In semileptonic decay modes, this often leads to the…
