Query: Scalar dark matter and Muon $g-2$ in a $U(1)_{L_{\mu}-L_{\tau}}$ model   We consider a simple scalar dark matter model within the frame of gauged
$L_{\mu}-L_{\tau}$ symmetry. A gauge boson $Z'$ as well as two scalar fields
$S$ and $\Phi$ are introduced to the Standard Model (SM). $S$ and $\Phi$ are SM
singlet but both with $U(1)_{L_{\mu}-L_{\tau}}$ charge. The real component and
imaginary component of $S$ can acquire different masses after spontaneously
symmetry breaking, and the lighter one can play the role of dark matter which
is stabilized by the residual $Z_2$ symmetry. A viable parameter space is
considered to discuss the possibility of light dark matter as well as
co-annihilation case, and we present current $(g-2)_{\mu}$ anomaly, Higgs
invisible decay, dark matter relic density as well as direct detection
constriants on the parameter space.
