We consider the model, which contains a nonminimal coupling of Dirac spinors to torsion. Due to the action for torsion that breaks parity, the leftright asymmetry of the spinors appears. This construction is used in order to provide dynamical electroweak symmetry breaking. Namely, we arrange all Standard Model fermions in the left-handed spinors. The additional technifermions are arranged in right-handed spinors. Due to the interaction with torsion, the technifermions are condensed and, therefore, cause appearance of the gauge boson masses. In order to provide all fermions with masses, we consider two possibilities. The first one is related to an additional coupling of a real massive scalar field to the considered spinors. The second possibility is to introduce the explicit mass term for the mentioned Dirac spinors composed of the Standard Model fermions and the technifermions.
