Abstract

Recent results on a study of exclusive processes of \(e^{+}e^{-}\) annihilation into hadrons below 2 GeV obtained at the SND detector are presented. The analyses are based on data collected at the VEPP-2000 collider. In particular, we present the measurements of the \(e^{+}e^{-}\to\eta\gamma\), \(e^{+}e^{-}\to\pi^{+}\pi^{-}\pi^{0}\), \(e^{+}e^{-}\to\omega\pi^{0}\) cross sections and the preliminary results on study of the \(e^{+}e^{-}\to\eta\pi^{+}\pi^{-}2\pi^{0}\) process. The results obtained are compared with previous measurements.

在VEPP-2000对撞机上用SND探测器研究\(\boldsymbol{e}^{\boldsymbol{+}}\boldsymbol{e}^{\boldsymbol{-}}\)湮灭成强子

本文介绍了在SND探测器上获得的2 GeV以下的\(e^{+}e^{-}\)湮灭成强子的独占过程的最新研究结果。这些分析是基于在VEPP-2000对撞机上收集的数据。特别地，我们给出了\(e^{+}e^{-}\to\eta\gamma\), \(e^{+}e^{-}\to\pi^{+}\pi^{-}\pi^{0}\), \(e^{+}e^{-}\to\omega\pi^{0}\)的截面测量和\(e^{+}e^{-}\to\eta\pi^{+}\pi^{-}2\pi^{0}\)过程研究的初步结果。所得结果与以往的测量结果进行了比较。
