The T2K CCQE selection and prospects for CCQE, NCE cross-section measurements
- Colorado State University, Department of Physics, Fort Collins, Colorado, U.S.A (United States)
A better understanding of the charge current quasi-elastic (CCQE) interaction channel will lead to a more precise ν{sub e} appearance and ν{sub μ} disappearance measurement at T2K. Measurements looking at the CCQE interaction using the near detector complex (ND280) help constrain cross-section uncertainties as well as the flux prediction at the far detector, Super-Kamiokande. The presented CCQE analysis is derived from a CC-inclusive selection using the tracking portion of ND280. The inclusive sample is broken into a CCQE-enhanced and CC non-QE like sample and each sample is used to constrain various parameters used for the far detector prediction. Future CCQE analyses using the tracker will either use the current selection or investigate newer selections for 2 track topologies. The neutral current equivalent to CCQE, neutral current elastic scattering (NCE), is being investigated using the pi-zero detector (POD). The NCE analysis selects a contained single track sample using muon/proton particle identification.
