Neutrino Shadow Play

NOTICE: THE SEMINAR WILL TAKE PLACE IN Rendal Building Room: REN-LT1





Neutrinos and antineutrinos generated by accelerators are unique tools to study leptonic CP violation (LCPV). By comparing neutrino and antineutrino energy spectra after oscillations, the delta CP-phase of the PMNS matrix can be measured. Limited by current technology, 
neutrinos are detected via their interactions with nuclear targets. In neutrino-nucleus interactions, initial-state uncertainties and final-state interactions have a big impact on the energy spectrum measurement. Studying such nuclear effects is essential for the discovery of LCPV.  

In a shadow play, a projected shadow tells a story; here we use eutrinos to project nuclear effects in neutrino interactions into the so-called single- and double-transverse kinematic imbalances. This new technique allows measurements of neutrino energy and nuclear effects to decouple, and hence has the potential to provide clean access to  LCPV with current technology.  In this seminar, the  idea and experimental status of this neutrino shadow play  will be discussed.
