Abstract
Multiply interacting massive particles (MIMPs) are heavy ($>{10}^{10}\text{ }\text{ }\mathrm{GeV}/{c}^{2}$) dark matter particles that interact strongly with regular matter, but may have evaded detection due to the low number density required to make up the local dark matter halo. These particles could leave tracklike signatures in current experiments, similar to lightly ionizing particles. We show that previously calculated limits from the majorana demonstrator on the flux of lightly ionizing particles can be used to exclude MIMP dark matter parameter space up to a mass of ${10}^{15}\text{ }\text{ }\mathrm{GeV}/{c}^{2}$. We also calculate limits from the standard XENON1T analysis in this high-mass regime, properly taking into account flux limitations and multiscatter effects. Finally, we show that a dedicated MIMP analysis using the XENON1T dark matter search could probe unexplored parameter space up to masses of ${10}^{18}\text{ }\text{ }\mathrm{GeV}/{c}^{2}$.
