Scalar dark matter: real vs complex

We update the parameter spaces for both a real and complex scalar dark matter via the Higgs portal. In the light of constraints arising from the LUX 2016 data, the latest Higgs invisible decay and the gamma ray spectrum, the dark matter resonant mass region is further restricted to a narrow window between $54.9-62.3$ GeV in both cases, and its large mass region is excluded until $834$ GeV and $3473$ GeV for the real and complex scalar, respectively.
