  "abstract": "We propose a setup involving Majorana bound states (MBS) hosted by a vortex on a superconducting surface of a 3D Topological Insulator (TI). We consider a narrow channel drilled across a TI slab with both sides covered by s-wave superconductor. In the presence of a vortex pinned to such a channel, it acts as a ballistic nanowire connecting the superconducting surfaces, with a pair of MBS localized in it. The energies of the MBS possess a 4\\pi-periodic dependence on the superconductive phase difference \\phi between the surfaces. It results in the appearence of an anomalous term in the current-phase relation, I_a(\\phi) for the supercurrent flowing along the channel between the superconductive surfaces. We have calculated the shape of the 4\\pi-periodic function I_a(\\phi), as well as the dependence of its amplitude on temperature and system parameters.",
