摘要
We present a measurement of the momentum spectra of ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$, ${\mathrm{K}}^{\ifmmode\pm\else\textpm\fi{}}$, ${\mathrm{p}}^{\ifmmode\pm\else\textpm\fi{}}$, $\mathrm{\ensuremath{\Lambda}}$, $\overline{\mathrm{\ensuremath{\Lambda}}}$, and ${\mathrm{K}}_{\mathrm{S}}^{0}$ produced in interactions of negatively charged pions with carbon nuclei at beam momenta of 158 and $350\text{ }\text{ }\mathrm{GeV}/c$. The total production cross sections are measured as well. The data were collected with the large-acceptance spectrometer of the fixed target experiment NA61/SHINE at the CERN SPS. The obtained double-differential $p\text{\ensuremath{-}}{p}_{\mathrm{T}}$ spectra provide a unique reference dataset with unprecedented precision and large phase-space coverage to tune models used for the simulation of particle production in extensive air showers in which pions are the most numerous projectiles.
