Search for subsolar-mass black hole binaries in the second part of Advanced LIGO's and Advanced Virgo's third observing run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1702

We describe a search for gravitational waves from compact binaries with at least one component with mass 0.2 $M_{\odot }$ -- $1.0M_{\odot }$ and mass ratio $q\ge 0.1$ in Advanced LIGO…
