Abstract: JUNO is a huge detector devoted to neutrino physics. It is
located in the South of China and employs 20kt of organic liquid
scintillator to detect neutrinos from different sources. In particular, its
main goal is to study in detail the oscillation phenomenon, looking at
the disappearance of anti-neutrinos produced by nuclear reactors
located ~52.5 Km away: this will lead to the measurement of the
oscillation parameters with an unprecedented precision and most
importantly to the determination of the neutrino mass ordering, one of
the most important unknowns in neutrino physics. JUNO has started
taking data on august 26th 2025. In this seminar, I will discuss the
working principles and the most outstanding characteristics of the JUNO
detector and I will show the first physics results obtained after only 2
months of data-taking.
