Fermions in the vortex background on a sphere
In 5+1 dimensions, we construct a vortex-like solution on a two-dimensional
sphere. We study fermionic zero modes in the background of this solution and
relate them to the replication of fermion families in the Standard Model. In
particular, using a compactified space removes the need for the difficult
localisation of gauge fields, while the present procedure (rather than naive
compactification on a disk) also removes spurious fermionic modes.Comment: 13 pages, 1 eps figure, JHEP3 style required, references adde
