Abstract

Cosmic Ray and neutrino oscillation physics can be studied by using atmospheric neutrinos. JUNO (Jiangmen Underground Neutrino Observatory) is a large liquid scintillator detector with low energy detection threshold and excellent energy resolution. The detector performances allow the atmospheric neutrino oscillation measurements. In this work, a discrimination algorithm for different reaction channels of neutrino-nucleon interactions in the JUNO liquid scintillator, in the GeV/sub-GeV energy region, is presented. The atmospheric neutrino flux is taken as reference, considering $\overset{(-)}{v_{μ}}$ $\mathop {{v_\mu }}\limits^{( - )}$ and $\overset{(-)}{v_{e}}$ $\mathop {{v_e}}\limits^{( - )}$ . The different temporal behaviour of the classes of events have been exploited to build a timeprofile-based discrimination algorithm. The results show a good selection power for $\overset{(-)}{v_{e}}$ $\mathop {{v_e}}\limits^{( - )}$ CC events, while the $\overset{(-)}{v_{μ}}$ $\mathop {{v_\mu }}\limits^{( - )}$ CC component suffers of an important contamination from NC events at low energy, which is under study. Preliminary results are presented.
