Query: Phenomenology of the Inert Doublet Model with a global U(1) symmetry   The inert doublet model is a minimal dark matter model with strong
theoretical motivations, where the stability of dark matter is usually achieved
by imposing a $Z_2$ parity. We promote the $Z_2$ parity into a global $U(1)$
symmetry and study its phenomenological implications. There are two
characteristic features of the model: both the CP-even and CP-odd neutral inert
scalars, $h_1$ and $h_2$, become DM candidates; the number of model parameters
is one less than that with $Z_2$ parity. We first analyze the constraints from
LEP experiments, electroweak precision tests, theoretical stability, Higgs
precision data, dark matter relic density, and direct detection experiments. It
is found that if the model is required to explain at least 10% of the observed
relic density, the theory is extremely limited such that the dark matter mass
is about $70\;{\rm GeV}$ and the charged Higgs boson is not very heavy.
Focusing on this narrow parameter space, we calculate the production cross
sections of almost all the possible mono-$X$ and mono-$XX'$ processes at the
LHC. The mono-$W\gamma$ process is shown to have high discovery potential with
the help of the decay of the intermediate-mass charged Higgs boson into $W^\pm
h_{1,2}$. A search strategy is designed to increase the potential discovery of
the model for the mono-$W\gamma$ signal at both the HL-LHC and the FCC-hh. The
optimal cut on $E_T^{\rm miss}/\sqrt{H_T}$ is suggested to maximize the signal
significance, being about $0.76$ at the HL-LHC and about $7.5$ at the FCC-hh.
