Measurement of θ₁₃ using RENO reactor neutrino events with neutron capture on hydrogen

RENO has been taking data since August, 2011 and successfully measured the smallest neutrino mixing angle, theta₁₃. This measurement was based on observed reactor neutrino events with neutron captures on gadolinium (n-Gd) in the target detector region. RENO also successfully measures the mixing angle from a reactor neutrino sample with neutron captures on hydrogen (n-H) in the gamma-catcher region. Due to a large accidental background in the n-H data sample, the analysis requires additional reduction of backgrounds. This independent measurement provides a valuable systematic cross-check of the θ₁₃ measurement using the n-Gd sample. In this paper, we present the results from the n-H analysis using the 500 days of data sample. (paper)
