1. Cosmology with a very light L μ − L τ gauge boson / Escudero, Miguel ; Hooper, Dan ; Krnjaic, Gordan ; Pierre, Mathias
In this paper, we explore in detail the cosmological implications of an abelian L μ − L τ gauge extension of the Standard Model featuring a light and weakly coupled Z ′. [...]

2. Severely Constraining Dark-Matter Interpretations of the 21-cm Anomaly / Berlin, Asher ; Hooper, Dan ; Krnjaic, Gordan ; McDermott, Samuel D.
The EDGES Collaboration has recently reported the detection of a stronger-than-expected absorption feature in the global 21-cm spectrum, centered at a frequency corresponding to a redshift of z17. [...]

3. Robust constraints and novel gamma-ray signatures of dark matter that interacts strongly with nucleons / Hooper, Dan ; McDermott, Samuel D.
Due to shielding, direct detection experiments are in some cases insensitive to dark matter candidates with very large scattering cross sections with nucleons. [...]

4. Toward (finally!) ruling out Z and Higgs mediated dark matter models / Escudero, Miguel ; Berlin, Asher ; Hooper, Dan ; Lin, Meng-Xiang
In recent years, direct detection, indirect detection, and collider experiments have placed increasingly stringent constraints on particle dark matter, exploring much of the parameter space associated with the WIMP paradigm [...]

5. PeV-scale dark matter as a thermal relic of a decoupled sector / Berlin, Asher ; Hooper, Dan ; Krnjaic, Gordan
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. [...]

6. Mixed dark matter in left-right symmetric models / Berlin, Asher ; Fox, Patrick J. ; Hooper, Dan ; Mohlabeng, Gopolang
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. [...]
