Measurement of the components of the tensor analyzing power in the reaction γd → ppπ − at high proton momenta

Results obtained by measuring three components of the tensor analyzing power in the reaction of π− -meson photoproduction on a deuteron at final-proton momenta between 300 and 700 MeV/c are presented. The measurements in question were performed at the VEPP-3 storage ring by using its internal deuterium-gas target featuring a tensor polarization with the aid of detection of two protons in coincidence. The experimental results obtained in this way are compared with their counterparts calculated theoretically.
