Study of the ρ\rho, ω\omega, ϕ→ηγ→7γ\phi\to\eta\gamma\to 7\gamma Decays with an SND Detector on a VEPP-2M Collider

The $e^+e^-\to\eta\gamma\to 7\gamma$ process was studied in the energy range $2E=600\div 1060$ MeV with an SND detector on a VEPP-2M $e^+e^-$ collider. The decay branching ratios $B(\phi\to\eta\gamma)=(1.343\pm 0.012\pm 0.055)\cdot 10^{-2}$, $B(\omega\to\eta\gamma)=(4.60\pm 0.72\pm 0.19)\cdot 10^{-4}$, and $B(\rho\to\eta\gamma)=(2.69\pm 0.32\pm 0.16)\cdot 10^{-4}$ were measured.Comment: 5 pages, 4 figure

СОВРЕМЕННАЯ СТРУКТУРА И ПРЕДПОЛАГАЕМАЯ ИСТОРИЯ ФОРМИРОВАНИЯ ЗЕМНОЙ КОРЫ ЮГО-ВОСТОКА СЕВЕРО-АЗИАТСКОГО КРАТОНА ВДОЛЬ ОПОРНОГО ПРОФИЛЯ 3-ДВ

The article presents results of specialized processing of the deep seismic profile along a part of Reference Profile 3-DV which crosses the Aldan-Stanovoi shield in the meridian direction and goes across its buried northern slope. The study is aimed at determining frequency-energy characteristics of the seismic wave field which are related to physical conditions of geological features of the crust. Based on analysis and interpretation of the dynamic profiles, it is possible to reveal and contour the Archean cores of consolidation of the Aldan shield and its buried continuation that is covered by sediments of the Middle Lena monocline and to input new facts in the proposed geodynamic model showing formation of the crust in the south-eastern segment of the North Asian craton.Специализированная обработка глубинного сейсмического разреза вдоль части опорного профиля 3-ДВ, пересекающей в меридиональном направлении Алдано-Становой щит и его северный погребенный склон, выполнена с целью определения частотно-энергетических характеристик сейсмического волнового поля, связанных с физическим состоянием геологических объектов земной коры. Результаты анализа и интерпретации полученных динамических разрезов позволили «увидеть» и оконтурить архейские ядра консолидации Алданского щита и его погребенного продолжения, скрытого осадками Среднеленской моноклизы, дополнить новыми фактами развиваемую геодинамическую модель формирования земной коры юго-восточной части Северо-Азиатского кратона.
