Chiral anomaly in Euler fluid and Beltrami flow

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.

The Beltrami Flow over Manifolds

Chiral anomaly in contorted spacetimes

The Dirac equation in Riemann–Cartan spacetimes with torsion is reconsidered. As is well-known, only the axial covector torsion A, a one-form, couples to massive Dirac fields. Using diagrammatic techniques, we show that besides the familiar Riemannian term only the Pontrjagin type four–form dA∧dA does arise additionally in the chiral anomaly, but not the Nieh–Yan term d ∗A, as has been claimed ...

Efficient Beltrami Flow in Patch-Space

The Beltrami framework treats images as two dimensional manifolds embedded in a joint features-space domain. This way, a color image is considered to be a two dimensional surface embedded in a hybrid special-spectral five dimensional {x, y,R,G,B} space. Image selective smoothing, often referred to as a denoising filter, amounts to the process of area minimization of the image surface by mean cu...

Beltrami Flow of an Unsteady Dusty Fluid Between Parallel Plates in Anholonomic Co-ordinate System

Abstract: An analytical study of Beltrami flow of viscous dusty fluid between two parallel plates has been studied. The flow is due to influence of movement of plates. Flow analysis is carried out using differential geometry techniques and exact solutions of the problem are obtained using Laplace Transform technique also which are discussed with the help of graphs drawn for different values of ...
