Search for the process $e^+e^-to eta^prime(958)$ with the CMD-3 detector

A search for the process $epemto eta^prime(958)$ in the $pipietatopipigammagamma$ final state has been performed with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider. Using an integrated luminosity of 2.69 pb$^{-1}$ collected at the center-of-mass energy Ecm = 957.68 MeV we set an upper limit for the product of electronic width and branching fractions $Gamma_{eta^prime(958)toepem}cdotBR_{eta^prime(958)topipieta}cdotBR_{etatogammagamma}<0.00041$ eV at 90% C.L.

Study of the process $e^+e^-to 3(pi^+pi^-)$ in the c.m.energy range 1.5--2.0 gev with the cmd-3 detector

The cross section of the process $e^+e^- to 3(pi^+pi^-)$ has been measured using 22 pb$^{-1}$ of integrated luminosity collected with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider in the c.m. energy range 1.5 -- 2.0 GeV. The measured cross section exhibits a sharp drop near the $pbar p$ threshold. A first study of dynamics of six-pion production has been performed.
