Abstract

Recent results on a study of exclusive processes of annihilation into hadrons with the SND detector at the VEPP-2000 collider at center-of-mass energies below 2 GeV are presented. In particular, we discuss new data on the processes \({{e}^{ + }}{{e}^{ - }} \to n\bar {n}\), \(p\bar {p}\), \(\eta \gamma \), \(\omega {{\pi }^{0}}\), \({{\pi }^{ + }}{{\pi }^{ - }}{{\pi }^{0}}\), and \({{\pi }^{ + }}{{\pi }^{ - }}{{\pi }^{0}}{{\pi }^{0}}\eta \).

在 VEPP-2000 上利用 SND 对 e+e- Annihilation into Hadrons 进行的研究

本文介绍了VEPP-2000对撞机上的SND探测器在质量中心能量低于2 GeV时对湮灭成强子的排他性过程进行研究的最新结果。特别是，我们讨论了关于以下过程的新数据：（{{e}^{ + }}{{e}^{ - }} \to n\bar {n}\）、（p\bar {p}\）、（\eta \gamma \）、\(\omega {{pi }^{0}}\),\({{pi }^{ + }}{{pi }^{ - }}{{pi }^{0}}\), and\({{pi }^{ + }}{{pi }^{ - }}{{pi }^{0}}{{\pi }^{0}}\eta \)。

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
