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

We present measurements of \(\rho ^0\), \(\omega \) and K\(^{*0}\) spectra in \(\pi ^{-} + \) C production interactions at 158 \(\text{ GeV }{/}\text{ c }\) and \(\rho ^0\) spectra at 350 \(\text{ GeV }{/}\text{ c }\) 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 and 350 \(\text{ GeV }{/}\text{ c }\) 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.
