To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN\u2019s Large Hadron Collider, using the FASER\u03bd detector. This study marks a significant step for particle physics research, enhancing our understanding of the universe.<\/p>\n<p>In a groundbreaking study, a team of researchers led by Associate Professor Akitaka Ariga from the Graduate School of Science, Chiba University, Japan, also affiliated with the Laboratory for High Energy Physics, University of Bern, Switzerland, and Associate Professor Tomoko Ariga from the Faculty of Arts and Science, Kyushu University, Japan, utilized the Forward Search Experiment (FASER) at CERN\u2019s Large Hadron Collider (LHC), to achieve the first direct observation of high energy electron and muon neutrino interactions at a particle collider. The team included Dr. Ken Ohashi from the Laboratory for High Energy Physics at the University of Bern, Dr. Hiroaki Kawahara from the Faculty of Arts and Science at Kyushu University, and Project-specific Assistant Professor Daiki Hayakawa from the Graduate School of Science, Chiba University, along with other members of the FASER collaboration. Their findings were published in the journal Physical Review Letters on July 11, 2024.<\/p>\n<h4 class=\"style4a\">Research-related inquiries<\/h4>\n<p><a href=\"https:\/\/hyoka.ofc.kyushu-u.ac.jp\/search\/details\/K006681\/english.html\">Tomoko Ariga, Associate Professor<\/a><br \/>\n <a href=\"https:\/\/www.artsci.kyushu-u.ac.jp\/english\/\">Faculty of Arts and Science<\/a><br \/>\nContact information can also be found in the <a href=\"https:\/\/www.kyushu-u.ac.jp\/f\/58291\/Final_CHIBJ_106_5_Press_Release_Clean.pdf\">full release<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Associate Professor Tomoko Ariga Faculty of Arts and Science Researchers obtain the first direct observation of electron and muon neutrino interactions at the Large Hadron Collider using the FASER\u03bd detector Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe.
