Abstract
We present results of a search for bosonic super-weakly interacting massive particles (BSW) as keV scale dark matter candidates that is based on an exposure of 97.7 kg·year from the COSINE experiment. In this search, we employ, for the first time, Compton-like as well as absorption processes for pseudoscalar and vector BSWs. No evidence for BSWs is found in the mass range from 10 keV/c2 to 1 MeV/c2, and we present the exclusion limits on the dimensionless coupling constants to electrons gae for pseudoscalar and κ for vector BSWs at 90% confidence level. Our results show that these limits are improved by including the Compton-like process in masses of BSW, above O(100 keV/c2). © 2023 authors. Published by the American Physical Society.
