Description
Sub-GeV dark matter (DM) has been gaining significant interest in recent years, since it can account for the thermal relic abundance while evading nuclear recoil direct detection constraints. Such light DM must carry a larger energy to be probed, either directly or through missing energy/momentum, making beam dump and fixed target experiments ideal for this mass range. Here, we extend the previous literature, which mainly focuses on the predicted experimental signals of scalar and fermionic DM, by considering simplified DM models in which the Standard Model is extended by one vector DM candidate along with one spin-1 mediator. In this analysis, we identify the parameters consistent with the observed relic abundance, calculate the relevant constraints from existing experiments and measurements, and predict the sensitivity of future experiments such as the upcoming LDMX. We find that spin-1 DM is testable by future experiments, and for certain spin-1 models, will be the first DM models probed by LDMX.
