Description
The current generation of long-baseline neutrino oscillation experiments
employ an off-axis (or ) beam produced by the decay of pions
created when a proton beam strikes a target. The beam is monitored at
detector facilities near the production point before travelling hundreds
of kilometres to a far detector. Aiming the beam centre slightly away
from the far detector provides the off-axis configuration which selects
a narrow energy band beam tuned to maximize the oscillation probability.
The status of these experiments will be presented.
The Tokai to Kamioka (T2K) experiment consists of a
beam produced at the Japan Proton Accelerator Research Centre (J-PARC)
in Tokai on the East coast of Japan, which is monitored by a suite of
detectors before travelling 295 km to the Super-Kamiokande
(SK) water Cerenkov detector. T2K has been in operation since 2010
and has been continually releasing new and exciting neutrino
oscillation results. The most recent precision appearance and
disappearance oscillation measurements as well as initial results
running the experiment in the beam configuration will be
presented.
The NO A experiment, utilizing the NuMI beam and a near detector at
Fermilab and a far detector at a distance of 810 km, began
operation in 2014. The current status of NO A will also be shown.
