Erratum: Strong new limits on light dark matter from neutrino experiments [Phys. Rev. D 100, 103011 (2019)]

Abstract

Due to a numerical error in our propagation code, the nuclear form factor was not properly accounted for when modeling propagation of dark matter (DM) through the Earth's crust. This same issue also affected the interaction of DM particles with target protons within a detector. That error, and the changes described here, affect only our treatment of DM-nucleon scattering and not DM-electron scattering. The most noticeable effect of fixing these errors is to reduce attenuation. So at large cross sections, our limits extend higher by a factor of up to 3.0. At small cross sections, our limits get weaker, but by a negligible amount. Here we revise Figs. 3-6. Figure
