摘要

在VEPP-2000 \(e^{+}e^{-}\)对撞机的SND探测器采集的积分光度146 pb \({}^{-1}\)的质心能量区，测量了\(e^{+}e^{-}\to\pi^{+}\pi^{-}2\pi^{0}\eta\)过程的横截面。所得截面拟合为共振为\(\rho(1700)\)和\(\rho(2150)\)的VMD模型。

Measurement of the \({e^{+}e^{-}\to}{\pi^{+}\pi^{-}2\pi^{0}\eta}\) Cross Section below \(\sqrt{{s}}{=2}\) GeV

The cross section for the \(e^{+}e^{-}\to\pi^{+}\pi^{-}2\pi^{0}\eta\) process is measured in the center-of-mass energy region 1.55–2 GeV for integrated luminosity 146 pb\({}^{-1}\) collected by the SND detector at the VEPP-2000 \(e^{+}e^{-}\) collider. The obtained cross section is fitted with the VMD model with \(\rho(1700)\) and \(\rho(2150)\) resonances.

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
