FIRST MEASUREMENT OF NEUTRINO AND ANTINEUTRINO ...

This thesis reports the measurement of muon neutrino and antineutrino disappearance and
electron neutrino and antineutrino appearance in a muon neutrino and antineutrino beam using
the T2K experiment. It describes a result in neutrino physics that is a pioneering indication
of charge-parity (CP) violation in neutrino oscillation  the first to be obtained from a single
experiment. Neutrinos are some of the most abundant-but elusive-particles in the universe  and
may provide a promising place to look for a potential solution to the puzzle of matter
antimatter imbalance in the observable universe. It has been firmly established that neutrinos
can change flavour (or 'oscillate')  as recognised by the 2015 Nobel Prize. The theory of
neutrino oscillation allows for neutrinos and antineutrinos to oscillate differently (CP
violation)  and may provide insights into why our universe is matter-dominated. Bayesian
statistical methods  including the Markov Chain Monte Carlo fitting technique  are used to
simultaneously optimise several hundred systematic parameters describing detector  beam  and
neutrino interaction uncertainties as well as the six oscillation parameters.
