Measurement of meson resonance production in π-+ C interactions at SPS energies: The NA61/SHINE Collaboration

We present measurements of ρ 0 , ω and K ∗ 0 spectra in π - + C production interactions at 158  GeV / c and ρ 0 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 x F in the range 0 < x F < 1 and 0 < x F &...

Description
Summary:We present measurements of ρ 0 , ω and K ∗ 0 spectra in π - + C production interactions at 158  GeV / c and ρ 0 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 x F in the range 0 < x F < 1 and 0 < x F < 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.
