Derivative expansion for the effective action of chiral gauge fermions. The normal parity component
نویسنده
چکیده
Explicit exact formulas are presented, up to fourth order in a chiral covariant derivative expansion, for the normal parity component of the Euclidean effective action of even-dimensional Dirac fermions. The bosonic background fields considered are scalar, pseudo-scalar, vector and axial vector. No assumptions are made on the internal symmetry group and, in particular, the scalar and pseudo-scalar fields need not be on the chiral circle. PACS numbers: 11.30.Rd 11.15.Tk 11.10.Kk

Explicit exact formulas are presented, for the leading order term in a chiral covariant derivative expansion, for the abnormal parity component of the effective action of twoand four-dimensional Dirac fermions in presence of scalar, pseudo-scalar, vector and axial vector background fields. The formulas hold for completely general internal symmetry groups and general configurations. In particula...

An explicit closed form is given for the parity anomalous component of the effective action of 2+1 dimensional fermions at finite temperature coupled to arbitrary external non Abelian and non stationary gauge field configurations. The calculation is based on a ζ-function regularization combined with a gauge covariant gradient expansion. The result checks the correct behavior under gauge and par...

An expansion in the number of spatial covariant derivatives is carried out to compute the ζ-function regularized effective action of 2+1-dimensional fermions at finite temperature in an arbitrary non-Abelian background. The real and imaginary parts of the Euclidean effective action are computed up to terms which are ultraviolet finite. The expansion used preserves gauge and parity symmetries an...
