JUNO Neutrino Mass Ordering Sensitivity

The Jiangmen Underground Neutrino Observatory is a 20~kton and $3%/sqrt{E ({rm MeV})}$ energy resolution multi-purpose liquid scintillator detector located at a 700~m underground laboratory in the south of China (Jiangmen city, Guangdong province). The exceptional energy resolution and the massive fiducial volume of the JUNO detector offer great opportunities for addressing many essential topics in neutrino and astroparticle physics. JUNO's primary goals are to determine the neutrino mass ordering and precisely measure the related neutrino oscillation parameters. With reactor neutrino data, JUNO can determine the neutrino mass ordering with great significance and measure the neutrino oscillation parameters $sin^2theta_{12}$, $Delta m^2_{21}$, and $Delta m^2_{31}/Delta m^2_{32}$ to the sub-percent precision. In addition, the atmospheric neutrino measurement at JUNO can also provide complementary and important information for neutrino physics. This poster includes the JUNO mass ordering sensitivity analysis of the reactor neutrinos based on the latest knowledge of the experiment. With careful background control, delicate energy response calibration, promising event reconstruction potential, and systematics suppression, JUNO will make a world-leading measurement of neutrino mass ordering and the neutrino oscillation parameters in the near future
