In this paper two examples are given of a chiral torsional anomaly Nieh-Yan (NY) topological invariant in Riemann-Cartan (RC) spacetime: in the first it is shown that a certain class of RC spacetime metrics yields a chiral torsional axial anomaly possessing a term proportional to E ⋅ B. Here E and B...
