Аннотация:We discuss the properties of the heavy vector fermions with bare Dirac mass terms and an SU(2)\ifmmode\times\else\texttimes\fi{}SU(2) global symmetry in the Yukawa interaction Lagrangian. Using the heat kernel expansion method we calculate their contributions to the low energy observables. We argue that these heavy fermions may be responsible for a soft dynamical symmetry breaking through their condensation. We also discuss the possibility of considering ordinary fermions as one part of the vector fermions within our model.
