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

Abstract

We describe a search for gravitational waves from compact binaries with at\nleast one component with mass 0.2 $M_\\odot$ -- $1.0 M_\\odot$ and mass ratio $q\n\\geq 0.1$ in Advanced LIGO and Advanced Virgo data collected between 1 November\n2019, 15:00 UTC and 27 March 2020, 17:00 UTC. No signals were detected. The\nmost significant candidate has a false alarm rate of 0.2 $\\mathrm{yr}^{-1}$. We\nestimate the sensitivity of our search over the entirety of Advanced LIGO's and\nAdvanced Virgo's third observing run, and present the most stringent limits to\ndate on the merger rate of binary black holes with at least one subsolar-mass\ncomponent. We use the upper limits to constrain two fiducial scenarios that\ncould produce subsolar-mass black holes: primordial black holes (PBH) and a\nmodel of dissipative dark matter. The PBH model uses recent prescriptions for\nthe merger rate of PBH binaries that include a rate suppression factor to\neffectively account for PBH early binary disruptions. If the PBHs are\nmonochromatically distributed, we can exclude a dark matter fraction in PBHs\n$f_\\mathrm{PBH} \\gtrsim 0.6$ (at 90% confidence) in the probed subsolar-mass\nrange. However, if we allow for broad PBH mass distributions we are unable to\nrule out $f_\\mathrm{PBH} = 1$. For the dissipative model, where the dark matter\nhas chemistry that allows a small fraction to cool and collapse into black\nholes, we find an upper bound $f_{\\mathrm{DBH}} < 10^{-5}$ on the fraction of\natomic dark matter collapsed into black holes.\n
