Measurement of the hadronic cross sections at Novosibirsk

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

Overview of SND hadronic cross section measurements

At the end of 2016 the SND detector resumed data taking at the upgraded VEPP-2000 e+e− collider. The analysis of data accumulated in 2010-2013 with an integrated lumonosity of 70 pb−1 is continuing. Recent results on measurements of various hadronic cross sections are presented

Recent results from SND experiment at VEPP-2000 collider

Preliminary results of the SND experiment at the VEPP-2000 e+e− collider are presented. Data corresponding to about 40 pb−1 of integrated luminosity were collected in the e+e− c.m. energy range from 1.05 to 2.00 GeV. The cross sections for e+e− → ωπ0, π+π−4π0, pp¯${m{par p}}$, nn¯${m{nar n}}$ have been measured

Precise measurements of the hadronic cross sections with the CMD-3 and SND detectors at the VEPP-2000 e+ e− collider

It’s good known the difference in 3.5 sigma between the muon (g – 2) experimental result and its calculation in Standard Model. To clarify this intriguing discrepancy the new stage of muon (g – 2) measurement is under preparation at Fermi National Laboratory. On other hand, regular data taking for measurements of hadron cross section production in e+ e− annihilations is under way since December 2010 at the electron-positron collider VEPP-2000 with the CMD-3 and SND detectors. The collected data sample corresponds to about 60 inverse picobarns of integrated luminosity per detector in the energy range from 0.32 up to 2 GeV. Preliminary analysis of various hadronic cross sections has been performed
