SUMMARY:Neutrinos from Tokai to Kamioka: Oscillations\, Interactions and t
 he search for CP-Violation - Stephen Dolan (CERN)

DESCRIPTION:The precise characterisation of neutrino oscillations offers a
  range of auspicious opportunities in the search for physics beyond the st
 andard model\, not least of which is measurement of the CP-violating compl
 ex phase in the neutrino mixing matrix (δCP) that governs associated brea
 king of the symmetry between matter and antimatter. Alongside measurements
  of many of the other mixing parameters\, the Tokai to Kamioka (T2K) exper
 iment has recently published\, in Nature\, the strongest constraint yet ma
 de on δCP\, excluding almost half of the possible values at 3σ confidenc
 e level\, through measurements of electron (anti)neutrino appearance in an
  accelerator-produced muon (anti)neutrino beam. But\, despite this conside
 rable achievement\, a comprehensive evaluation of CP-violation in the neut
 rino sector will only be possible with a significant reduction of the asso
 ciated systematic uncertainties. The most pressing of these uncertainties 
 concern the details of the neutrino-nucleus interactions in the one-to-few
  GeV region that are used to analyse neutrino oscillations. Currently our 
 inability to model such interactions threatens to pre-maturely limit the s
 ensitivity of current and future neutrino oscillation experiments. However
 \, novel neutrino-nucleus scattering measurements\; new detector technolog
 y\; and collaboration with the nuclear physics community provides a path f
 orward to understanding neutrino interactions at the required level. I wil
 l present T2K’s latest analysis of neutrino oscillations\, demonstrating
  the critical role of neutrino-nucleus interaction modelling\, before also
  showing some of T2K’s recent neutrino interaction measurements and its 
 strategy for the future.
