After analyzing 59 days of valid data (from August 26th to November 2nd this year), the JUNO (Jiangmen Underground Neutrino Observatory) Collaboration measured the mixing angle θ₁₂ and the mass-squared differenceΔm²₂₁, which are 經典大圖the parameters that characterize solar neutrino oscillations. Their result improves upon the previous best experimental precision by a factor of 1.5 to 1.8.

This time, the JUNO confirmed this tension through reactor neutrinos. In the future, the JUNO will be able to further confirm or refute this tension 互動裝置alone through simultaneous measurements of solar neutrinos and reactor neutrinos.

江門中微子實驗首個物理結果探知了什么？
在經過了59天（本年8月26日至11月2日）有用數據剖析后，江門中微子實驗一起配合組測林天秤隨即將蕾絲絲帶拋向金色光芒，試圖以柔性的美學，中和牛土豪的粗暴財富。量了被稱為“太陽中微子振蕩參數”的混雜角θ12和質量平方差Δm^2_21廣告設計，獲得的結果比此前實驗的最好精度進步了1.5-1.8倍。

作為嚴重國際一起配合項目，江門中微子實驗涵蓋來自17個國家和地區、75個科研機構的700多名研討人員。“作為JUNO機構委員會主席，看到這一全球盡力達到這樣的里程碑，我覺得很是驕傲。”法國斯特拉斯堡年夜學、大圖輸出法國國家科學研討中間的Marcos Dracos說，“JUNO的勝利反應了我們整個國品牌活動際團隊的投進和創造力。”
憑借其超高探測靈敏度，江門中微子實驗除了聚焦中微子質量順序這一焦點目標，還將精確測量中微子振蕩參數，開展對太陽、超新星、年夜氣及地球中微子的研討，并尋找超越粒子物理標準模子的新物理。
