Measurement of the T20 Component of the Tensor Analyzing Power of the Incoherent Photoproduction of a π– Meson on a Deuteron

This is the authors' abstract. We don't add key points for this paper.

New results have been presented for the T20 component of the tensor analyzing power of the γd → ppπ– reaction measured in the photon energy range from 300 to 600 MeV. The data have been obtained from the statistical sample collected at the VEPP-3 accelerator in 2021. The T20 component has been separated using the asymmetry of the reaction yield, which is due to change in the sign of the tensor polarization of the deuterium target. The experimental data have been compared to the simulation within the spectator model including the interaction between particles in the final state.
