Research publish by the T2k institute ( Tokai-to-Kamioka) in Japan has highlighted unusual partical behaviour – particularly that associated with neutrino behaviour. Such experiments have elucidated some theoretical problems that are encountered when solely relying on the Standard Model of particle physics.
The research data set, which looks at violation of charge-parity symmetry, was the first to simultaneously collate data from neutrino and antineutrino activity in a collider environment.

The experiment which was hosted by KEK and the ICRR was carried out at the J-PARC Japan Proton Accelerator Research Complex. The use of high-intensity beams of muon neutrinos and high-intensity muon antineutrino beams gave ground-breaking results.
During the journey of the neutrino particles, scientists observed that the particles changed ‘flavor’. In this respect, muon neutrinos changed to electron neutrinos and muon antineutrinos changed to electron antineutrinos. Such phenomena reveals an imbalance between particles and anti-particles and points to a descrepency in the Standard Model of particle physics.
