Abstract

The reaction e+e−→ π+ π−π0η has been studied in the experiment with the SND detector at the VEPP-2000 e+ e− collider. The reaction proceeds via the four intermediate states: ωη, φη, a0ρ, and structureless π+π−π0η state, which may be, for example, ρ(1450) with ρ(1450) → ρ(770)η. The total e+e−→ π+π−π0η cross section and cross section for the four intermediate states have been measured and fitted in the vector meson dominance model.

Abstract

Since December 2010 the CMD-3 and SND detectors detectors collect data at the VEPP-2000 electron-positron collider. In 2013-2015 the injection facility of the collider has undergone an upgrade of the injection system. The new BINP injection complex has been connected to the VEPP-2000 collider, so the restrictions connected to the lack of positrons and limited beam energy transfer do not apply any more. The collider luminosity in whole energy range is restricted now only by beam-beam effects. VEPP-2000 collider started to collect data with two detectors at 2016 year. The collected data sample since 2010 corresponds more than 100 pb-1 of integrated luminosity per detector in the c.m. energy between 0.32 and 2GeV. We will report here results of analysis of various hadronic cross sections from detectors both published and preliminary. These measurements are important by themselves and also because of the implications for anomaly of the magnetic moment of a muon (g-2) discrepancy.

Abstract

Two experiments, CMD-3 and SND, collected over 100 pb−1 in total taking data in 2011-2013 at the VEPP-2000 electron-positron collider. The data sample covers the whole available c.m. energy range from 0.32 GeV to 2.0 GeV. An upgrade of VEPP-2000 started in the second half of 2013, aimed at the luminosity increase up to 10 times at 2.0 GeV. Data taking is expected to resumed in 2015. The current results of analysis of the collected data for various modes of e+ e− → hadrons are discussed.

In 2017 the detector SND resumed data taking at the VEPP-2000 e+e−collider after its upgrade. Using of a new positron source allows significantly increase collider luminosity. We report the current status of the experiment and recent result of data analysis, in particular, on the processes e+e−→π+π−, nn‾, K+K−η, π+π−η, KSKLπ0, π+π−π0η, π0γ, ωπ0, and η→e+e−.

Abstract

Recent results on various cross sections of e+e−→hadronsobtained with the SND and CMD3 detectors at the VEPP-2000 collider in the energy range up to 2 GeV are presented. The final states studied include e+e−→π+π−, K+K−, π+π−π0, π+π−π0π0, ηπ+π−, ωη, ηγand others. The measured cross sections are important since they contribute to the total hadronic cross section, muon g-2 and parameters of excited vector mesons. The nucleon-antinucleon production at threshold was also studied.
