"Mixed Dark Matter in Left-Right Symmetric Models"

 

 

 

We explore models of mixed dark matter in left-right theories, motivated by the recently reported diboson and dijet excesses in Run 1 data at ATLAS and CMS. Contrary to similar studies that implement pure multiplets, WIMP-nucleon scattering proceeds at tree-level, and hence the projected reach of future direct detection experiments like LUX-ZEPLIN will cover large regions of parameter space for TeV-scale thermal dark matter. Decays of the heavy charged W0 boson to particles in the dark sector can potentially shift the right-handed gauge coupling to larger values when fixing to the observed Run 1 excesses, thus favoring the theoretically attractive scenario gR = gL. This region of parameter space may be probed by future collider searches for new Higgs bosons.
