Study of the process e super(+)e super(-) arrow right 3( pi super(+) pi super(-))e+e- arrow right 3( pi + pi -) in the c.m. energy range 1.5-2.0 GeV with the CMD-3 detector

The cross section of the process e super(+)e super(-) arrow right 3( pi super(+) pi super(-))e+e- arrow right 3( pi + pi -) has been measured using a data sample of 22 pb super(-1)22 pb-1 collected with the CMD-3 detector at the VEPP-2000 e super(+)e super(-)e+e- collider. 7956 signal events are sel...

Zusammenfassung:	The cross section of the process e super(+)e super(-) arrow right 3( pi super(+) pi super(-))e+e- arrow right 3( pi + pi -) has been measured using a data sample of 22 pb super(-1)22 pb-1 collected with the CMD-3 detector at the VEPP-2000 e super(+)e super(-)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[macr] threshold. A first study of dynamics of six-pion production has been performed.
