Here, [zeta] acquires a nonminimal kinetic term of the form [omega]([phi]) due to its interaction with [phi]([phi], [zeta] can be identified with the scalar dilaton field and the pseudoscalar
axion field, respectively), while *[F.sup.[mu]v] = (1/2)[[epsilon].sup.[mu]v[kappa][lambda]][F.sub.[kappa][lambda]] is the Hodge-dual Maxwell field strength.
where [I.sub.AB] denotes the pseudoscalar
forming the minimal subspace which contains A and B.
, electro-weak radiative corrections to scalar, pseudoscalar
, and tensor interactions of any origin induce contributions to P,T-violating e - q interactions.

Equation (2.5) demonstrates that a P-odd T-odd interaction does modify, as claimed in , the energy dependence of the P-odd asymmetry associated with the pseudoscalar

where the superscripts i and j refer to four operators in the effective Lagrangian given by (4) (the tensors related to the scalar and pseudoscalar
operators can be understood through the relations given by (21) and (22)); in the SM, i = j corresponds to the operator [bar.p][[gamma].sub.[mu]] (1 - [[gamma].sub.5])b[bar.l][[gamma].sup.[mu]](1 - [[gamma].sub.5])[nu].
(The possibility of using a pseudoscalar
factor is not discussed here because this work aims to examine the parity conserving electromagnetic interactions of a quantum mechanical particle.) It is shown below how these two requirements impose dramatic constraints on acceptable quantum mechanical equations of motion of a charged particle.
Here [psi] is a Majorana spinor field, S is a scalar field, and P is a pseudoscalar
where E, p, m, t and r are respectively energy, momentum, mass, time, space and the symbols [+ or -]1, [+ or -]i, [+ or -]i, [+ or -]j, [+ or -]k, [+ or -]i, [+ or -]j, [+ or -]k are used to represent the respective units required by the scalar, pseudoscalar
, quaternion and multivariate vector groups.
