Observation of ¿_µ¿¿_e Oscillation in the T2K Experiment (eBook, PDF)

• Format: PDF

Produktbeschreibung

In this thesis the

author contributes to the analysis of neutrino beam data collected between 2010

and 2013 to identify ¿_µ¿¿_e events at the Super-Kamiokande detector. In particular,

the author improves the pion-nucleus interaction uncertainty, which is one of

the dominant systematic error sources in T2K neutrino oscillation measurement.

In the thesis, the measurement of ¿_µ¿¿_e oscillation in the T2K (Tokai to

Kamioka) experiment is presented and a new constraint on d_CP is obtained. This

measurement and the analysis establish, at greater than 5s significance, the

observation of ¿_µ¿¿_e oscillation for the first time in the world. Combining

the T2K ¿_µ¿¿_e oscillation measurement with the latest findings on oscillation

parameters including the world average value of ¿13 from reactor experiments,

the constraint on the value of d_CP at the 90% confidence level is obtained.

This constraint on d_CP is an important step towards the discovery of CP

violation in the lepton sector.
