Neutrino interactions: Effects on T2K Oscillation Analyses

Luke Pickering, Michigan State University

Abstract

Neutrino oscillation experiments are chasing the answer to a number of fundamental questions, most importantly: Is there enough Charge-Parity violation in the lepton sector to explain the deficit of anti-matter in the observable universe?

In the 1–5 GeV neutrino energy region—where current and planned accelerator-based beams peak—neutrino–matter interaction theory is non- perturbative, and currently available models fail to predict the extant data well. This is problematic for oscillation analyses that depend strongly on interpreting observations through such models. Over the next decade, interaction-model uncertainties will set the limit on the precision of oscil- lation experiments.

The Tokai-to-Kamioka (T2K) experiment, which has been taking data since 2010, is one such oscillation experiment. The latest analysis shows tantalizing hints of differences in the oscillation of neutrinos and anti- neutrinos—i.e. lepton sector CP violation. This talk will discuss what we are currently learning with the T2K data, how the neutrino interaction uncertainties are parameterized, and what the future holds for the field.
