Kōichirō Nishikawa
Kōichirō Nishikawa ( Japanese 西川 公 一郎 , Nishikawa Kōichirō ; * 1949 ; † November 2018 ) was a Japanese elementary particle physicist, known for his contributions to neutrino physics . He was a professor at Kyoto University .
For 2016 he and the K2K and T2K team received the Breakthrough Prize in Fundamental Physics with other neutrino experiments. In 2005 he received the Nishina Prize and in 2016 the Bruno Pontecorvo Prize .
He was the speaker of the K2K experiment of a neutrino beam from the proton synchrotron of the KEK to the Super Kamiokande detector in Kamioka (1999 to 2005). The K2K team at the KEK confirmed the neutrino oscillations already observed by Kamiokande II in atmospheric neutrinos with greater accuracy . On the successor T2K (neutrino rays from the J-PARC accelerator to the Super-Kamiokande detector; in operation from 2010) neutrino oscillations with a defined start and end flavor of the neutrinos were observed and 3-generation neutrinos confirmed according to the standard model.
