Axion-Assisted Production of Sterile Neutrino Dark Matter
Asher Berlin, Dan Hooper
Sterile neutrinos can be generated in the early universe through oscillations with active neutrinos and represent a popular and well-studied candidate for our universe's dark matte…
Toward (Finally!) Ruling Out Z and Higgs Mediated Dark Matter Models
Miguel Escudero, Asher Berlin, Dan Hooper +1
In recent years, direct detection, indirect detection, and collider experiments have placed increasingly stringent constraints on particle dark matter, exploring much of the parame…
Thermal Dark Matter From A Highly Decoupled Sector
Asher Berlin, Dan Hooper, Gordan Krnjaic
It has recently been shown that if the dark matter is in thermal equilibrium with a sector that is highly decoupled from the Standard Model, it can freeze-out with an acceptable re…
Neutrino Oscillations as a Probe of Light Scalar Dark Matter
Asher Berlin
We consider a class of models involving interactions between ultra-light scalar dark matter and Standard Model neutrinos. Such couplings modify the neutrino mass splittings and mix…
Mixed Dark Matter in Left-Right Symmetric Models
Asher Berlin, Patrick J. Fox, Dan Hooper +1
Motivated by the recently reported diboson and dijet excesses in Run 1 data at ATLAS and CMS, we explore models of mixed dark matter in left-right symmetric theories. In this study…
PeV-Scale Dark Matter as a Thermal Relic of a Decoupled Sector
Asher Berlin, Dan Hooper, Gordan Krnjaic
In this letter, we consider a class of scenarios in which the dark matter is part of a heavy hidden sector that is thermally decoupled from the Standard Model in the early universe…
The Diphoton and Diboson Excesses in a Left-Right Symmetric Theory of Dark Matter
Asher Berlin
We explore the possibility that the recently reported diphoton excess at ATLAS and CMS can be accommodated within a minimal extension of a left-right symmetric model. Our setup is…
