Abstract
We present a new analysis of previously published SuperCDMS data using a profile likelihood framework to search for sub-GeV dark matter (DM) particles through two inelastic scattering channels: bremsstrahlung radiation and the Migdal effect. By considering these possible inelastic scattering channels, experimental sensitivity can be extended to DM masses that are undetectable through the DM-nucleon elastic scattering channel, given the energy threshold of current experiments. We exclude DM masses down to 220 MeV/𝑐² at 2.7×10⁻³⁰ cm² via the bremsstrahlung channel. The Migdal channel search provides overall considerably more stringent limits and excludes DM masses down to 30 MeV/𝑐² at 5.0×10⁻³⁰ cm².

Data Availability
The two supplemental files contain data for the rock composition and the geology of the region around the lab site. It is better presented in this form than trying to make a large table in the paper. These are just flat CSV files.
