Study of the process e+e−→3(π+π−) in the c.m. energy range 1.5–2.0 GeV with the CMD-3 detector
Get PDFAbstractThe cross section of the process e+e−→3(π+π−) has been measured using a data sample of 22 pb−1 collected with the CMD-3 detector at the VEPP-2000 e+e− collider. 7956 signal events are selected in the center-of-mass energy range 1.5–2.0 GeV. The measured cross section exhibits a sharp drop near the pp¯ threshold. A first study of dynamics of six-pion production has been performed

KEDR detector at the VEPP-4M collider continues deliver precision measurements of the charmonium family. Results of the ψ(2S ) and ψ(3770) study are presented. Two energy scans of a center-of-mass energy range from 1 GeV to 2 GeV has been performed by the VEPP2000 collider with an integrated luminosity of about 35 pb−1, collected by each of the CMD-3 and SND detectors. This paper reports the latest results from VEPP-2000 obtained by the CMD-3 collaboration
