T2K’s Col­la­bo­ra­tion published new results in the pre­sti­gious scien­ti­fic jour­nal Nature regar­ding the lar­gest para­me­ter limit to date deter­mi­ning the vio­la­ting phase of sym­me­try between mat­ter and antimat­ter in neu­trino oscil­la­tions. Almost half of the possi­ble values ​​of the para­me­ter δCP were exc­lu­ded, thus reve­aling the basic owner­ship of neu­trinos that had not been measu­red so far.
