My presentation will consist of two different parts. Firstly, I shall describe a low energy, effective field theory of superconductivity in which a topological mass term is radiatively in- duced in one loop effective action by coupling an antisymmetric tensor field with the vorticity current of charged Dirac fermions in the Lagrangian. In the non-relativistic limit, the static effective potential shows a linear, always attractive term between two electrons. In the second part, I shall talk about the Anomalous Chromomagnetic Moment (ACM) of the quarks, the dependence on a small, gauge invariant mass of the gluon. The results are plotted at two different momentum transfers, at q 2 = −M2 Z as well as at q 2 = −m2 t.
