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 &...

and

using the NA61/SHINE spectrometer at the CERN SPS. Spectra are presented as a function of the Feynman’s variable
