At 19:09(JST), the first neutrino beam production is confirmed by observing the muons by the muon monitor system installed at the most downstream of the neutrino beam line of J-PARC. The neutrino beam will be used to study nature of neutrino masses in the T2K experiment. ----------------------------------------------------------- [Editorial Note] ----------------------------------------------------------- In case you do not wish to receive this Newsletter in the future, please send an email to news-l-ctl@ml.j-parc.jp and simply write one sentence in the body of the message as unsubscribe If you wish to receive, write one sentence in the body of the message as subscribe You can get a help with a sentence of "help" in the body.
