Abstract
We discuss the type of the general macroscopic parity-violating
effects, when there is the current along the vortex, which is concentrated in
the vortex core. We consider vortices in chiral superfluids with Weyl
points. In the vortex core the positions of the Weyl points form the skyrmion
structure. We show that the mass current concentrated in such a core is
provided by the spectral flow through the Weyl points according to the
Adler-Bell-Jackiw equation for chiral anomaly.
