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 theoreticallyand 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 80 GeV) and the mass splitting between the neutral scalars is also roughly 40 − 80 GeV, a signal at the 3σ to 12σ significance level can be observed with 100 fb −1 of integrated luminosity. In addition, even if the mass splitting between the neutral scalars is larger than M Z , a signal of more than 3σ can be observed as long as the mass of the dark-matter candidate is around 40 GeV.

In this work, we investigate the prospects for detecting the Inert Doublet Model via the trilepton channel at the LHC. We present a set of representative benchmark scenarios in which all applicable constraints are satisfied, and show that in some of these scenarios, it is possible to obtain a signal at the 5σ significance level or better with integrated luminosity of 300 fb

We explore electroweak precision observables (EWPO) and B-physics observables (BPO) in the CMSSM, the mGMSB and the mAMSB. We perform a χ 2 analysis based on the combination of current EWPO and BPO data. For the first time this allows the comparison of the mGMSB and mAMSB in terms of EWPO and BPO with the CMSSM. We find that relatively low mass scales in all three scenarios are favored. However, the current data from EWPO and BPO can hardly exclude any parameters at the level of ∆χ 2 = 9. Remarkably the mAMSB scenario, despite having one free GUT scale parameter less than the other two scenarios, has a somewhat lower total minimum χ 2 . *
