Strong gravity with torsion and the Cabibbo angle

The classical field equations of the strong gravity theory are modified by introducing spin and torsion so as to resemble the field equations of the Einstein-Cartan theory. The effects of the hadronic spin upon the strong metric are evaluated using a semiclassical approximation, and it is pointed out that the torsion contributions are not negligible. A possible interpretation of the Cabibbo angle as a strong gravity correction of the weak semileptonic Lagrangian is suggested.
