Abstract
New measurements of hadron production with a proton beam on a 2 cm carbon target at 31 GeV/c performed by the NA61/SHINE collaboration are shown. The inelastic and production cross section are presented. Multiplicities of π±, K±, KS0, proton and Λ are shown. These measurements are fundamental to reduce the uncertainties on the neutrino flux at the T2K experiment. The procedure used to tune the T2K flux prediction with the measured spectra is explained as well.

Summary
T2K (Tokai-to-Kamioka) is an off-axis long-baseline neutrino experiment in Japan that aims to precisely measure the parameters of the PMNS matrix and to look for the first indication of CP violation in the lepton sector by measuring νμ disappearance and νe appearance in a νμ beam. A muon neutrino beam is produced at the J-PARC Main Ring (MR) accelerator that provides a 30 GeV proton-beam interacting on a long carbon target (1.9λL). The neutrino beam is directed 2.5◦ off the axis between the target and the far detector 295 km away. This configuration produces a narrow-band beam with a peak energy of about 0.6 GeV which is exactly on the first νμ → νe oscillation maximum. The NA61/SHINE experiment at the CERN SPS measures the hadronic production with a proton beam of the same momentum as in T2K on a graphite target [5]. New results on multiplicities of charged hadrons as well as the total p+C production cross section are shown
