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. Baryogenesis and dark matter from B mesons / Elor, Gilly ; Escudero, Miguel ; Nelson, Ann E.
We present a new mechanism of baryogenesis and dark matter production in which both the dark matter relic abundance and the baryon asymmetry arise from neutral B meson oscillations and subsequent decays. [...]

3. The dispirited case of gauged U(1) B − L dark matter / Escudero, Miguel ; Witte, Samuel ; Rius, Nuria
We explore the constraints and phenomenology of possibly the simplest scenario that could account at the same time for the active neutrino masses and the dark matter in the Universe within a gauged U(1) B − L symmetry, namely right-handed neutrino dark matter. [...]

4. Sterile neutrino portal to Dark Matter II: exact dark symmetry / Escudero, Miguel ; Rius, Nuria ; Sanz, Verónica
We analyze a simple extension of the standard model (SM) with a dark sector composed of a scalar and a fermion, both singlets under the SM gauge group but charged under a dark sector symmetry group. [...]

5. Sterile neutrino portal to Dark Matter I: the U(1) B − L case / Escudero, Miguel ; Rius, Nuria ; Sanz, Verónica
In this paper we explore the possibility that the sterile neutrino and Dark Matter sectors in the Universe have a common origin. [...]

6. 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 [...]
