Solar axion search by annual modulation with XMASS-I detector

Research output: Contribution to journalConference articlepeer-review


Kaluza-Klein (KK) axions produced in the Sun have been proposed to explain several astrophysical anomalies. We searched for the decay of such solar KK axions using 832 × 359 kg • days XMASS-I data. No significant event rate modulation is found, and we set the first experimental constraint on KK axion photon-coupling of 4.8 × 10"12 GeV-1 for a KK axion number density of (math) = 4.07 × 1013 m3 at 90% C.L.
