Double Chooz (DC) is a reactor antineutrino disapparence experiment, aiming to precisely measure the neutrino mixing angle theta13. DC employs a two-identical-detector design, which could provide flux (cross section) and detection systematics cancellation. DC uses inverse beta decay (IBD) to tag neutrino signals with high precision due to the coincidence. The delayed neutron signal can be generated by being captured by hydrogen or Gadolinium. Therefore, two independent channels, n-Gd and n-H can be implemented in DC.
In this seminar, DC combines the two neutron capture channels at the event selection level. This combination increases the statistics significantly, thus able to provide better two-detector measurement. A summary of past results as well as the new oscillation analysis will be shown.
I joined the PhD physics program in Illinois Institute of Technology in 2010 and was sent to be a lab student in Argonne National Lab since summer 2011. I strongly participated in the Double Chooz experiment, partially CALICE hadron detector built and a small amount of work in the JUNO experiment. I finished my thesis with Dr.Zelimir Djurcic and Dr.Maury Goodman in Argonne and obtain PhD in the summer of 2016. Currently I am a postdoc in the neutrino-nucleon decay group in Stony Brook university working on the T2K and DUNE experiments, advised by Prof.Chang Kee Jung.
