Signals of composite electroweak-neutral Dark Matter: LHC/Direct Detection interplay

Understand

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 $V$, 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 $V$, showing its possible discovery at the maximal LHC energy with about 100 fb^{-1} of integrated luminosity.
