The latest report on T2K results has been published[1], and it looks good for the upcoming long neutrino baseline experiment at DUNE and T2HK. The result may suggest that these two upcoming experiments may finally nail down
CP violation in neutrinos, which will be a substantial advancement in our understanding on why there are more mater than antimatter in our universe.
The discovery of substantial leptonic CP violation would be
groundbreaking. Its observation, together with evidence that a quantity
known as lepton number has been violated (that is, not conserved), would
provide strong circumstantial evidence for leptogenesis as the origin
of the matter–antimatter imbalance.
