Updates and latest results of the SENSEI experiment.

ORAL

Abstract

The sub-electron resolution of Skipper-CCDs enables the detection of energy transfers as low as a few eV, such as what is expected from sub-GeV dark matter interacting with electrons in a silicon target. SENSEI pioneered implementing these sensors in rare-event searches, producing several world-leading results with this technology and setting a new benchmark with the lowest reported dark current in a silicon detector. In this talk, we present the latest results and status of SENSEI and discuss the leading constraints produced after the first and second science runs at SNOLAB.
