The tensor force is included in a large amplitude in pion exchange interactions. The importance of the tensor force is known in light nuclei where ab-initio type calculation of nucleus can be made. However the mean field model or the shel model that describe the heavier nuclei do not include the tensor force explicitly. One of the most important effect of the tensor force is the creation of...

It contains vorticity terms and a 4-dimensional Euclidean Berry monopole which gives axial anomaly.
