Description
Weyl symmetry can be naturally realised in Cartan-Einstein gravity both at the kinematical and dynamical level. The symmetry can be naturally extended to matter fields by a suitable generalization of covariant derivative and by supplementing a dilaton field. Fermionic matter sources skew symmetric torsion while scalar matter sources vectorial torsion trace (gauge fields do not trace torsion). This implies that, when matter fields are integrated out, vectorial torsion and skew symmetric torsion become dynamical. In this talk I will present preliminary results on physical implications of torsion trace and skew symmetric torsion.
