Description
The Daya Bay experiment has made a measurement of sin22θ13 using neutron capture on hydrogen (nH). This measurement is largely independent of the more precise Daya Bay result using captures on gadolinium (nGd). The resulting observation of reactor antineutrino disappearance offers strong confirmation of the nGd result and provides the world’s second most precise measurement of sin22θ13. New techniques were developed to deal with the more challenging analysis due to
larger backgrounds, longer capture time and larger energy leakage.
