Abstract
The off-axis near detector ND280 of the T2K experiment contains several materials that act as targets for neutrino interactions. One of the most efficient of these is the lead in the electromagnetic calorimeter, ECal. Although neutrino interaction cross sections are important to measure in their own right, and in addition are essential for the progress of high-precision measurements in neutrino oscillation experiments, cross sections on lead have not been well measured to date. Previous T2K PhD students have developed algorithms for measuring the neutrino interaction rate and cross section on lead in the ECal. Joe will continue this work with the aim of producing a rate and/or cross-section publication. This measurement will contribute not only to T2K but to the field of neutrino precision measurements in general.
This project also will contain an element of service work to the experiment. This work will involve software development and maintenance of the ECal event reconstruction code, detector operator shifts on site in Tokai, and expert detector shifts with responsibility for the day-to-day checks and calibrations of several of the ND280 sub-detectors.

| PI Contribution | I work on the fit to the near detector data of the T2K experiment which aims to constrain beam flux and neutrino interaction model parameters. This allow a reduction on the uncertainty of the measurement of neutrino oscillation parameters. Along with running the near detector fit as part of the 2020 oscillation analysis, I have included a new style of parameter in the fit which is used to fit to the nuclear binding energy parameters. |
| Collaborator Contribution | Working groups in T2K usually span various institutions and countries. These are the primary source of support for the research as they have the hands on expertise and knowledge to guide the research. The oscillation analysis is the final step in a long chain of work from all of the collaborators and requires input from several hundred people. From detector maintenance and data acquisition to interaction modelling and computer modelling. |
| Impact | T2K outputs many publications which individual collaborators have various degrees of involvement in. Whilst my primary research is yet to be included in a published analysis, I have contributed to a paper which has been accepted in principle by Nature about the search for CP violation in neutrino oscillations. |
