Daya Bay neutrino oscillation progress based on neutron captured on hydrogen

Not scheduled


Mr Jinjing Li (Tsinghua University, department of engineering physics)


The Daya Bay reactor neutrino experiment is the first experiment that measured a nonzero value
for the $\theta_{13}$ neutrino mixing angle in 2012. Antineutrinos from six 2.9
GWth reactors are detected in eight functionally identical antineutrino detectors
deployed in two near ($\sim 500$ m) and one far (1648 m) underground
experimental halls. The near-far arrangement of antineutrino detectors allows for a relative
measurement by comparing the observed antineutrino rates at various baselines. In 2014, the
Daya Bay experiment reported an independent measurement of the nonzero neutrino oscillation
parameter $\theta_{13}$, utilizing the data set of neutron captured on hydrogen (nH) with distinct
systematic uncertainties from the data set of neutrons captured on gadolinium, and has been
improving this measurement since then. In this poster, I shall show the latest progress of the Daya
Bay nH neutrino oscillation analysis with improved statistics and systematic control.


Progress of neutrino oscillation from Daya Bay via neutron captured on hydrogen will be shown.
