Last T2K paper of the year 2019 published !
Just in time for celebrating, we are proud to be part of the last T2K publication of the 2019 year entitled "Measurement of neutrino and antineutrino neutral-current quasi-elastic-like interactions on oxygen by detecting nuclear deexcitation gamma rays"
Neutral current interactions at the neutrino energies of the T2K experiment are difficult to observe because their final state particles are either neutral or charged but often below the Cherenkov threshold and therefore difficult to detect in the far Superkamiokande detector. Instead, in the published paper the quasi-elastic neutral current (NCQE) interactions have been detected using Cherenkov light arising from the electromagnetic cascade produced by gamma rays emitted from the deexcitation of the recoil nucleus. This represents a new method which has proven to be very effective to study neutrino flavor oscillations!
The paper has been published in Physical Review D.
