Query: Muonphilic Dark Matter explanation of gamma-ray galactic center excess:
  a comprehensive analysis   The Galactic center gamma-ray excess (GCE) is a long-standing unsolved
problem. One of candidate solutions, the dark matter (DM) annihilation, has
been recently tested with other astrophysical observations, such as AMS-02
electron-positron spectra, Fermi Dwarf spheroidal galaxies gamma ray data, and
so on. It has been claimed that only the DM annihilation to a muon-pair, namely
muonphilic DM, is compatible with the null detection of all the corresponding
astrophysical measurements [Di Mauro and Winkle (2021)]. On the other hand, a
muonphilic DM model may also lead to a signal in the recent muon g-2
measurement or the latest PandaX-4T limit. In this work, we comprehensively
study interactions between DM and muon, including different DM and mediator
spins. In agreement with GCE (not only $2\mu$ but also $4\mu$ final states), we
test these interactions against all the thermal DM constraints. Our results
show that only the parameter space near the mediator resonance region can
explain GCE and relic density simultaneously. Regardless of the DM spin, only
the interactions with the spin-0 mediator can explain the recent muon g-2
excess on top of GCE, relic density, and other DM and mediator constraints.
