Cross section measurement of the charged current muon antineutrino single π- production at T2K
T2K experiment is a long baseline neutrino oscillation experiment in Japan. Cross section measurements of (anti)neutrino interactions in sub-GeV to few GeV energy range allow to constrain the systematic uncertainties in the oscillation analysis. Single charged pion production is a relevant interaction mode at this energy scale.In this seminar I will present the cross section measurement of single π- production in muon antineutrino CC interaction on hydrocarbon. The cross section is reported as double-differential in muon kinematical variables i.e. momentum and cosine of the muon emission polar angle.
