چکیده
The cross section of the process e+ e– → π+ π– π0 was measured with CMD-3 detector at electron-positron collider VEPP-2000 in ω meson energy region based on data collected 2013–2018 and corresponding to an integrated luminosity 40 pb–1. parameters ω-meson: Mω = 782.67 ± 0.01 0.1 MeV, Γω 8.56 0.02 0.07 σ0(ω π) 1629 3 36 nb precision match or even exceeding previous are obtained.

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
