P and T-violating massive spin one particle

We analyze a system of parity and time reversal violating massive spin one particle in (2+1) dimensions. We find that its gyromagnetic ratio is one and that there is asymmetry in the energy levels between positive and negative values if the external magnetic field is present. The P and T-violating current, Hall current without the magnetic field, is present as well. Classical solutions of the effective Lagrangian are found also and the oscillations around the classical solutions are analyzed. (author)
