Title: Hadro-Production Measurements to Characterize the T2K Neutrino Flux with the NA61 Experiment at the CERN SPS

Abstract

As the intensity of neutrino beams produced at accelerators increases, the systematic errors due to the poor characterization of the neutrino flux become a limiting factor for high precision neutrino oscillation experiments like T2K. This limitation comes mainly from the poor knowledge of production cross sections for pions and kaons at the same energy and over the same phase-space yielding these neutrino beams. Therefore new hadro-production measurements are mandatory. The NA61/SHINE is a large acceptance hadron spectrometer at the CERN-SPS designed for the study of the hadronic final states produced in interactions of various beam particles (protons, pi's, and heavy ions) with a variety of fixed targets at the SPS energies. Ongoing measurements with the NA61 detector for characterizing the neutrino beam of the T2K experiment at J-PARC are introduced. These measurements are performed using a 30 GeV proton beam impinging on carbon targets of different lengths, including a replica of the T2K target. The performance of the NA61 detector and preliminary NA61 measurements from the 2007 run are presented.
