The inert doublet model is one of the simplest and most versatile scenarios for physics beyond the standard model. In this work, we examine the prospects for detecting the additional fields of this model at the LHC in the dilepton channel. We investigate a wide variety of theoretically and phenomenologically motivated benchmark scenarios, and show that within regions of model parameter space in which the dark-matter candidate is relatively light (between 40 and 80Â GeV) and the mass splitting between the neutral scalars is also roughly 40-80Â GeV, a signal at the 3σ to 12σ significance level can be observed with 100fb-1 of integrated luminosity. In addition, even if the mass splitting between the neutral scalars is larger than MZ, a signal of more than 3σ can be observed as long as the mass of the dark-matter candidate is around 40Â GeV.
