Measurement of Meson Resonance Production in ${\pi }^{-}+$C Interactions at SPS energies

We present measurements of ${\rho }^0$, $\omega$ and K${}^{\ast 0}$ spectra in ${\pi }^{-}+$C production interactions at 158 GeV/c and ${\rho }^0$ 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 $x_{\text{F}}$ in the range $0 < x_$\text{F}$ < 1$and$0 < x_$\text{F}$ < 0.5$ for 158 GeV/c 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.
