DESCRIPTION:Speakers: Alberto Garfagnini (Università di Padova)\n\n\n \n
 The seminar will be held in English\nJust two months after its completion\
 , the next-generation neutrino detector JUNO (Jiangmen Underground Neutrin
 o Observatory) in southeastern China has already achieved extraordinary pr
 ecision\, determining some fundamental solar neutrino oscillation paramete
 rs with unprecedented accuracy.On the occasion of the publication in Natur
 e of the article presenting the results from the first two months of opera
 tion\, the journal dedicated the cover of its June 11\, 2026 issue to JUNO
 .To share this important result with the department\, Alberto Garfagnini i
 s organizing a seminar to be held on July 9 at 11 a.m. in Aula Rostagni.\n
 Abstract\nThe Jiangmen Underground Neutrino Observatory (JUNO)\, located i
 n southern China\, has started data taking at the end of August 2025. Desi
 gned to study electron antineutrinos produced by nearby nuclear power plan
 ts\, JUNO is built around a 20\,000-ton liquid scintillator detector viewe
 d by about20\,000 photomultiplier tubes. Installed 700 meters underground 
 and shielded by an ultrapure water pool\, the detector achieves an excepti
 onal radiopurity and background suppression required for precision neutrin
 o measurements. Only two months after the start of data taking\, JUNO meas
 ured two of the key neutrino oscillation parameters with unprecedented pre
 cision. The results have been recently published in Nature and featured on
  the journal's cover\, highlighting their scientific significance. Very re
 cently\, the collaboration released new results based on 207 days of data 
 taking\, confirming percent-level precision on the two main oscillation pa
 rameters. For the first time\, JUNO also measured the third mass-squared d
 ifference\, $\\Delta m_{31}^{2}$\, with approximately 1% precision. This m
 easurement provides information on the neutrino mass ordering and currentl
 y favors the normal ordering with a significance of 2.3$\\sigma$.\nThese r
 esults will be presented in the seminar and future prospects of JUNO physi
 cs highlighted.\n \n \n\nhttps://indico.dfa.unipd.it/event/1876/
