  In this study of the Inert Doublet Model (IDM), we propose that the dijet +
missing transverse energy channel at the Large Hadron Collider (LHC) will be an
effective way of searching for the scalar particles of the IDM. This channel
receives contributions from gauge boson fusion, and $t-$channel production,
along with contributions from $H^+$ associated production. We perform the
analysis including study of the Standard Model (SM) background with assumed
systematic uncertainty, and optimise the selection criteria employing suitable
cuts on the kinematic variables to maximise the signal significance. We find
that with high luminosity option of the LHC, this channel has the potential to
probe the IDM in the mass range of up to about 400 GeV, which is not accessible
through other leptonic channels. In a scenario with light dark matter of mass
about 65 GeV, charged Higgs in the mass range of around 200 GeV provides the
best possibility with a signal significance of about $2\sigma$ at an integrated
luminosity of about 3000 fb$^{-1}$.
