New measurements of the <math><msub><mrow><mi>T</mi></mrow><mrow><mn>20</mn></mrow></msub></math> component of tensor analyzing power in the reaction <math><mi>γ</mi><mi>d</mi><mo>→</mo><mi>p</mi><mi>p</mi><msup><mrow><mi>π</mi></mrow><mrow><mo>−</mo></mrow></msup></math> for photon energies <math><mn>400</mn><mo>−</mo><mn>700</mn></math> MeV are presented. The experiment was carried out on an internal tensor-polarized gas deuterium target of the VEPP-3 electron storage ring in 2023 with the use of tagged quasi-real photons and two-proton coincidence. For determination of <math><msub><mrow><mi>T</mi></mrow><mrow><mn>20</mn></mrow></msub></math>, the asymmetry caused by a change of the sign of the tensor polarization of the deuteron target was measured. The new data are compared with the results of theoretical calculations based on the quasi-free approximation including πN and NN rescattering effects.
