Challenges for an axion explanation of the muon measurement
Manuel A. Buen-Abad, JiJi Fan, Matthew Reece +1
The discrepancy between the muon measurement and the Standard Model prediction points to new physics around or below the weak scale. It is tantalizing to consider the loop ef…
Dark Matter Substructure under the Electron Scattering Lamppost
Jatan Buch, Manuel A. Buen-Abad, JiJi Fan +1
We study the mutual relationship between dark matter-electron scattering experiments and possible new dark matter substructure nearby hinted by the Gaia data. We show how kinematic…
Galactic Origin of Relativistic Bosons and XENON1T Excess
Jatan Buch, Manuel A. Buen-Abad, JiJi Fan +1
We entertain the exotic possibility that dark matter (DM) decays or annihilations taking place in our galaxy may produce a flux of relativistic very weakly-coupled bosons, axions o…
Common Origin of Warm Dark Matter and Dark Radiation
Manuel A. Buen-Abad, Raymond T. Co, Keisuke Harigaya
We consider a cosmological scenario where a relativistic particle and a stable massive particle are simultaneously produced from the decay of a late-decaying particle after Big-Ban…
Dynamical axion misalignment with small instantons
Manuel A. Buen-Abad, JiJi Fan
We present a new mechanism to relax the initial misalignment angle of the QCD axion and raise the cosmological bound on the axion decay constant. The QCD axion receives a contribut…
Cannibal Dark Matter and Large Scale Structure
Manuel A. Buen-Abad, Razieh Emami, Martin Schmaltz
Cannibals are dark matter particles with a scattering process that allows three particles to annihilate to two. This exothermic process keeps the gas of the remaining particles war…
