Limit on the Axion Decay Constant from the Cooling Neutron Star in Cassiopeia A
TL;DR: In this paper, the axion decay constant of the supernova remnant Cassiopeia A (Cas A) was investigated in the presence of axion emission, taking account of the temperature evolution in the whole life of the Cas A NS.

Self-interacting dark matter and muon ( g − 2) in a gauged U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ model
TL;DR: In this paper, a self-interacting dark matter model is proposed to explain the observed muon anomalous magnetic moment, which is based on a generalized version of the standard model, where a vector-like pair of fermions and a new Higgs boson are introduced to break the symmetry.
Self-interacting dark matter and muon $g-2$ in a gauged U$(1)_{L_{\mu} - L_{\tau}}$ model
TL;DR: In this paper, a self-interacting dark matter model is proposed to explain the observed muon anomalous magnetic moment, which is based on a gauged U$(1)_{L_{\mu} - L_{\tau}}$ extension of the standard model, where a vector-like pair of fermions as the dark matter candidate and a new Higgs boson to break the symmetry.
Light axinos from freeze-in: production processes, phase space distributions, and Ly-α forest constraints
TL;DR: In this article, the authors considered the freeze-in production of 7 keV axino dark matter (DM) in the supersymmetric Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) model in light of the 3.5 keV line excess.

Light Axinos from Freeze-in: production processes, phase space distributions, and Ly-$\alpha$ forest constraints
TL;DR: In this article, the phase space distribution of axino dark matter in the supersymmetric Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) model was investigated.
