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. Freezing-in dark matter through a heavy invisible Z / Bhattacharyya, Gautam ; Dutra, Maíra ; Mambrini, Yann ; Pierre, Mathias
We demonstrate that in a class of the U(1) extension of the Standard Model (SM), under which all the Standard Model matter fields are uncharged and the additional neutral gauge boson Z couples to a set of heavy nonstandard fermions, dark matter (DM) production mediated by Z can proceed through the generation of generalized Chern-Simons (GCS) couplings.

3. Flavourful Z ′ portal for vector-like neutrino dark matter and R K * $$ {R}_{K^{\left(*\right)}} $$ / Falkowski, Adam ; King, Stephen ; Perdomo, Elena ; Pierre, Mathias
We discuss a flavourful Z ′ portal model with a coupling to fourth-family singlet Dirac neutrino dark matter. [...]

4. Spin-2 portal dark matter / Bernal, Nicolás ; Dutra, Maíra ; Mambrini, Yann ; Olive, Keith ; et al
We generalize models invoking a spin-2 particle as a mediator between the dark sector and the standard model. [...]

9. Re-opening dark matter windows compatible with a diphoton excess / Arcadi, Giorgio ; Ghosh, Pradipta ; Mambrini, Yann ; Pierre, Mathias
We investigate a simple setup in which an excess in the di-photon invariant mass distribution around 750 GeV, as seen by the ATLAS and CMS collaborations, is originated through a pair of collimated photon pairs. [...]
