Abstract
Using the cross-correlation data from the first three observing runs of the LIGO-Virgo-KAGRA collaboration, we search for a gravitational-wave background (GWB) from primordial black holes, arising from the superposition of compact binary coalescence events. We consider both early and late binary formation mechanisms and perform Bayesian parameter inference. From the nondetection of the GWB, we provide constraints on the fraction of primordial black holes contributing to the present dark matter energy density.
