Query: An update on the two singlet Dark Matter model   We revisit the two real singlet extension of the Standard Model with a
$Z_2\times Z_2^\prime$ symmetry. One of the singlet scalars $S_2$, by virtue of
an unbroken $Z_2^\prime$ symmetry, plays the role of a stable dark matter
candidate. The other scalar $S_1$, with spontaneously broken $Z_2$-symmetry,
mixes with the SM Higgs boson and acts as the scalar mediator. We analyze the
model by putting in the entire set of theoretical and recent experimental
constraints. The latest bounds from direct detection Xenon1T experiment
severely restricts the allowed region of parameter space of couplings. To
ensure the dark matter satisfies the relic abundance criterion, we rely on the
Breit-Wigner enhanced annihilation cross-section. Further, we study the
viability of explaining the observed gamma-ray excess in the galactic center in
this model with a dark matter of mass in the $\sim 36-51$ GeV window and
present our conclusions.
