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…
Effects of Mass Varying Neutrinos on Cosmological Parameters as determined from the Cosmic Microwave Background
Akshay Ghalsasi, Ann E. Nelson
In models with a light scalar field (the `acceleron') coupled to neutrinos, neutrino masses depend on neutrino density. The resulting coupled system of mass varying neutrinos (MaVa…
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…
Planning the Future of U.S. Particle Physics (Snowmass 2013): Chapter 4: Cosmic Frontier
J. L. Feng, S. Ritz, J. J. Beatty +18
These reports present the results of the 2013 Community Summer Study of the APS Division of Particles and Fields ("Snowmass 2013") on the future program of particle physics in the…
