| Description | Speaker: Asher Berlin Title: Cavendish Tests of Millicharged Particles Room: 3024, with Zoom link https://ucdavis.zoom.us/j/186024391 Host: Hsin-Chia Cheng Abstract: The simplest cosmologies motivate the consideration of dark 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 terrestrial temperatures, well below the thresholds of most existing dark matter detectors. This motivates the consideration of alternative detection techniques sensitive to a terrestrial population of slowly-moving dark matter particles. In this talk, I will focus on such a population of millicharged particles, and show how reinterpretations of Cavendish tests of Coulomb's Law, first performed in the late 18th century, provide some of the strongest bounds on this largely unexplored parameter space. |
