Measurement of meson resonance production in π− + C interactions at SPS energies

We present measurements of ρ0, ω and K*0 spectra in π− + C production interactions at 158 GeV/c and ρ0 spectra at 350 GeV/c using the NA61/SHINE spectrometer at the CERN SPS. Spectra are presented as a function of the Feynman’s variable xF in the range 0 < xF < 1 and 0< xF< 0.5 for 158 and 350 GeV/c respectively. Furthermore, we show comparisons with previous measurements and predictions of several hadronic interaction models. These measurements are essential for a better understanding of hadronic shower development and for improving the modeling of cosmic ray air showers.
