The ATLAS Diboson Resonance in Non-Supersymmetric SO(10)
Jason L. Evans, Natsumi Nagata, Keith A. Olive +1
SO(10) grand unification accommodates intermediate gauge symmetries with which gauge coupling unification can be realized without supersymmetry. In this paper, we discuss the possi…
Scenarios for Gluino Coannihilation
John Ellis, Jason L. Evans, Feng Luo +1
We study supersymmetric scenarios in which the gluino is the next-to-lightest supersymmetric particle (NLSP), with a mass sufficiently close to that of the lightest supersymmetric…
Beyond the CMSSM without an Accelerator: Proton Decay and Direct Dark Matter Detection
John Ellis, Jason L. Evans, Feng Luo +3
We consider two potential non-accelerator signatures of generalizations of the well-studied constrained minimal supersymmetric standard model (CMSSM). In one generalization, the un…
Signatures of Leptoquarks at the LHC and Right-handed Neutrinos
Jason L. Evans, Natsumi Nagata
In this paper, we argue that an extension of the Standard Model with a single leptoquark and three right-handed neutrinos can explain the excess in the first-generation leptoquark…
SU(5) Grand Unification in Pure Gravity Mediation
Jason L. Evans, Natsumi Nagata, Keith A. Olive
We discuss the proton lifetime in pure gravity mediation models with non-universal Higgs soft masses. Pure gravity mediation offers a simple framework for studying SU(5) grand unif…
Affleck-Dine Sneutrino Inflation
Jason L. Evans, Tony Gherghetta, Marco Peloso
Motivated by the coincidence between the Hubble scale during inflation and the typical see-saw neutrino mass scale, we present a supergravity model where the inflaton is identified…
