Predicted direct detection of a new dark matter WIMP in experiments currently taking data

The amazing sensitivity of current direct-detection experiments has imposed stringent constraints on any theoretical dark matter candidate. In particular, the most simplistic models with supersymmetry (susy) and weakly interacting massive particles (WIMPs) have been disconfirmed by experiment, and this has led to increasing pessimism about their existence. But there are still quite compelling arguments for susy and WIMPs. Here we discuss a multicomponent dark matter scenario with two WIMPs: the neutralino of susy and the higgson of an extended Higgs sector. Both these particles are stable because neither can decay into a set of particles containing the other. We discuss the potential for observing this second particle, which has a mass of about 70 GeV, in direct detection experiments which are currently taking data -- principally LZ, XENONnT, and PandaX-4T.
