Abstract:

We analyze LIGO data from run O4a to search for excess transient noise in DARM induced by cosmic ray showers. The cosmic ray detector at LIGO Hanford and its characterization with data is described. Several methods are discussed and implemented in attempts to uncover induced noise. We find no evidence for an association of transient noise in DARM with cosmic rays, including dense showers of ~1000 cosmic ray muons incident near a suspended test mass.
