Description
We present direct detection constraints on sub-GeV dark matter interacting with electrons using the DAMIC@Snolab experiment – which utilizes high resistivity, scientific grade CCDs to image ionization deposits produced by particle interactions within the devices. Using a relatively novel methodology of placing constraints based on leakage current, we report preliminary limits probing new parameter space for dark matter-electron scattering for masses roughly between 0.6 MeV $c^{-2}$ to 5 MeV $c^{-2}$, along with limits on the flux of Lightly Ionizing Particles from fractional charge e$^-$/30 to e$^-$/10000 using a similar analysis.
