Signals of composite electroweak-neutral Dark Matter: LHC/Direct Detection interplay
arXiv:1001.3149 · doi:10.1016/j.physletb.2010.04.010
Abstract
In a strong-coupling picture of ElectroWeak Symmetry Breaking, a composite electroweak-neutral state in the TeV mass range, carrying a global (quasi-)conserved charge, makes a plausible Dark Matter (DM) candidate, with the ongoing direct DM searches being precisely sensitive to the expected signals. To exploit the crucial interplay between direct DM searches and the LHC, we consider a composite iso-singlet vector , mixed with the hypercharge gauge field, as the essential mediator of the interaction between the DM particle and the nucleus. Based on a suitable effective chiral Lagrangian, we give the expected properties and production rates of , showing its possible discovery at the maximal LHC energy with about 100 fb^{-1} of integrated luminosity.
