▁few ▁Ge V . ▁ ▁Since ▁the ▁start ▁of ▁the ▁data ▁taking ▁in ▁ 2 0 1 0 , ▁the ▁T 2 K ▁experiment ▁succeeded ▁to ▁provide ▁a ▁list ▁of ▁world - class ▁results : ▁ ▁The ▁confirm ation ▁of ▁electron ▁neut r ino ▁appearance ▁in ▁the ▁mu on ▁neut r ino ▁beam ▁( → ), ▁which ▁was ▁the ▁first ▁time ▁when ▁neut r inos ▁produced ▁in ▁one ▁flav our ▁was ▁explicitly ▁observed ▁in ▁another ▁flav our . ▁ ▁The ▁most ▁precise ▁measurement ▁of ▁the ▁ θ 2 3 ▁parameter . ▁ ▁The ▁first ▁significant ▁constraint ▁on ▁the ▁ δ CP ▁parameter , ▁responsible ▁for ▁the ▁matter - ant im atter ▁asym met ry ▁in ▁the ▁neut r ino ▁sector . ▁ ▁Lim its ▁on ▁a ▁ster ile ▁neut r ino ▁oscill ation ▁parameters ▁based ▁on ▁studies ▁in ▁the ▁near ▁N D 2 8 0 ▁ ▁and ▁far ▁Super - K ami ok ande ▁ ▁detect ors . ▁ ▁Vari ous ▁cross - section ▁measurements ▁of ▁electron ▁and ▁mu on ▁neut r ino ▁and ▁ant ine ut r ino , ▁including ▁inclus ive ▁charged ▁current ▁( CC ) ▁interactions , ▁CC ▁interactions ▁without ▁p ions ▁ ▁and ▁with ▁single ▁p ion ▁in ▁the ▁final ▁state , ▁coh er ent ▁p ion ▁production , ▁neutral ▁current ▁interactions , ▁etc . ▁on ▁different ▁targets ▁such ▁as ▁carbon , ▁water ▁and ▁iron . ▁ ▁Future ▁up gr ades ▁of ▁T 2 K ▁is ▁expected ▁to ▁provide ▁further ▁const rain ▁on ▁the ▁ δ CP ▁phase ▁by
