Chiral Anomaly and Γ3π *

Measurement of the γ3π process has revealed a possible conflict with what should be a solid prediction generated by the chiral anomaly. We show that inclusion of appropriate energy-momentum dependence in the matrix element reduces the discrepancy. ∗ Research supported in part by the National Science Foundation.

Generalized Nambu system on S and spinors

It is shown that the manifold S can be equipped with a natural Nambu structure arising out of a cross product on the tangent space. Further, the group action of SU(2) on S is shown to be Nambu action. Moreover, we compare the action of SU(2) on spinors with that of a Nambu system.

A Note on Metric Connections for Chiral and Dirac Spinors

By means of (1.2) and (1.3) each matrix S ∈ SL(2,C) is associated with some matrix S ∈ SO(1, 3,R) so that we can write S = φ(S), see [1], [2], and [3] for detailed description of this construction. Let M be a space-time manifold, i. e. a four-dimensional orientable manifold equipped with a pseudo-Euclidean Minkowski-type metric g and carrying a special smooth geometric structure which is called...

Torsion , topology and CPT anomaly in two - dimensional chiral U ( 1 ) gauge theory

Torsion, topology and CPT anomaly in two-dimensional chiral U (1) gauge theory Abstract We consider the CPT anomaly of two-dimensional chiral U (1) gauge theory on a torus with topologically nontrivial zweibeins corresponding to the presence of spacetime torsion. The resulting chiral determinant can be expressed in terms of the standard chiral determinant without torsion, but with modified spin...

Generalized Killing Spinors in Dimension 5

We study the intrinsic geometry of hypersurfaces in Calabi-Yau manifolds of real dimension 6 and, more generally, SU(2)-structures on 5manifolds defined by a generalized Killing spinor. We prove that in the real analytic case, such a 5-manifold can be isometrically embedded as a hypersurface in a Calabi-Yau manifold in a natural way. We classify nilmanifolds carrying invariant structures of thi...
