Dibaryon structure in the energy and angular dependence of the tensor polarization t20 in π‐d elastic scattering?

The tensor polarization t20 of the recoil deuterons from π+‐d elastic scattering has been measured between Tπ=110 and 150 MeV. The angular distribution in the backward hemisphere is observed at the lower and higher energies. An excitation curve of t20 at θc2cm=150° shows a clear peak near the mass 2.14 GeV with a structure about 10 MeV wide. A phase‐shift analysis of all available π+‐d scattering energy and angular dependence is believed to manifest evidence for non‐conventional dynamics.
