Reducing cosmological small scale structure via a large dark matter-neutrino interaction: constraints and consequences
Bridget Bertoni, Seyda Ipek, David McKeen +1
Cold dark matter explains a wide range of data on cosmological scales. However, there has been a steady accumulation of evidence for discrepancies between simulations and observati…
CP Violation in Pseudo-Dirac Fermion Oscillations
Seyda Ipek, David McKeen, Ann E. Nelson
Supersymmetric theories with a symmetry have Dirac gauginos, solve the supersymmetric flavor and CP problems, and have distinctive collider signatures. However when superg…
Leptophobic Dark Matter at Neutrino Factories
Brian Batell, Patrick deNiverville, David McKeen +2
High-luminosity fixed-target neutrino experiments present a new opportunity to search for light sub-GeV dark matter and associated new forces. We analyze the physics reach of these…
A Renormalizable Model for the Galactic Center Gamma Ray Excess from Dark Matter Annihilation
Seyda Ipek, David McKeen, Ann E. Nelson
Evidence for an excess of gamma rays with O(GeV) energy coming from the center of our galaxy has been steadily accumulating over the past several years. Recent studies of the exces…
Constraints on muon-specific dark forces
Savely G. Karshenboim, David McKeen, Maxim Pospelov
The recent measurement of the Lamb shift in muonic hydrogen allows for the most precise extraction of the charge radius of the proton which is currently in conflict with other dete…
