Abstract
We examine possible experimental signatures that may be exploited to search
for stable supermassive particles with electric charges of $O(1)$ in future
underground experiments, and the upcoming JUNO experiment in particular. The
telltale signal would be a correlated sequence of three or more nuclear recoils
along a straight line, corresponding to the motion of a non-relativistic
($\beta <10^{-2}$) particle that could enter the detector from any direction.
We provide some preliminary estimates for the expected event rates.
