TL;DR: The spherical neutral detector (SND) as mentioned in this paper operates at VEPP-2M collider in Novosibirsk studying e + e − annihilation in the energy range up to 1.4
Abstract: The Spherical Neutral Detector (SND) operates at VEPP-2M collider in Novosibirsk studying e + e − annihilation in the energy range up to 1.4 GeV. Detector consists of a fine granulated spherical scintillation calorimeter with 1632 NaI(Tl) crystals, two cylindrical drift chambers with 10 layers of sense wires, and a muon system made of streamer tubes and plastic scintillation counters. The detector design, performance, data acquisition and processing are described.

TL;DR: In this paper, a narrow energy interval near the $\phi$-meson was scanned and the observed cross-section revealed, at the level of three standard deviation, the interference effect caused by the $e^+e^- \to \omega \pi^0 \to π^0 π-gamma$ process.
Abstract: The $e^+e^- \to \omega \pi^0 \to \pi^0 \pi^0 \gamma$ process was investigated in the SND experiment at the VEPP-2M collider. A narrow energy interval near the $\phi$-meson was scanned. The observed cross-section reveals, at the level of three standard deviation, the interference effect caused by $\phi \to \pi^0\pi^0\gamma$ decay. The cross-section parameters, as well as the real and imaginary parts of the $\phi$-meson related amplitude, were measured.

TL;DR: In this paper, a new spectrometric channel of the SND electromagnetic calorimeter is described, which is designed for the study of the e+e−→ n process at the VEPP-2000 e−e− collider.
Abstract: A new spectrometric channel of the SND electromagnetic calorimeter is described. It has a time resolution of about 1.3 ns at an energy deposition in the calorimeter crystal of 100 MeV and an amplitude resolution of about 250 keV. The new channel is designed, in particular, for the study of the e+e−→ n process at the VEPP-2000 e+e− collider.
