Measurement of charged pion cross section in proton carbon interaction at 30-GeV with the NA61/SHINE apparatus

Among other goals, the NA61/SHINE (SHINE SPS Heavy Ion and Neutrino Experiment) detector at CERN SPS aims at precision hadro-production measurements to characterise the neutrino beam of the T2K experiment at J-PARC. These measurements are performed using a 30 GeV proton beam produced at the SPS with a thin carbon target and a full T2K replica target. Preliminary spectra of < and + inclusive inelastic cross section were obtained from pilot data collected in 2007 with a 2 cm thick target (4% of the i nteraction length). After a description of the SHINE detector and its particle identification capabilities, results from three different analysis are presented.
