SUMMARY:Cavendish Tests of Millicharged Relics\, Theory Seminar (High 
 Energy/Cosmology)\, Asher Berlin\, Fermilab
DESCRIPTION: The simplest cosmologies motivate the consideration of da
 rk matter subcomponents that interact significantly with normal matter
 . Moreover\, such strongly-coupled relics may have evaded detection to
  date if upon encountering the Earth they rapidly thermalize down to t
 errestrial temperatures\, well below the thresholds of most existing d
 ark matter detectors. This motivates the consideration of alternative 
 detection techniques sensitive to a terrestrial population of slowly-m
 oving dark matter particles. In this talk\, I will focus on such a pop
 ulation of millicharged particles\, and show how reinterpretations of 
 Cavendish tests of Coulomb's Law\, first performed in the late 18th ce
 ntury\, provide some of the strongest bounds on this largely unexplore
 d parameter space.
