摘要

We present measurements of rho(0), omega and K*(0) spectra in pi(-) + C production interactions at 158GeV/c and rho(0) spectra at 350GeV/c using the NA61/ SHINE spectrometer at the CERN SPS. Spectra are presented as a function of the Feynman's variable xF in the range 0 < xF < 1 and 0 < xF < 0.5 for 158 and 350GeV/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.
