Massive Particle's Tunnelling from Black Hole with Topological Defect

We extend Zhang and Zhao's recent work to black hole with topological defect whose Arnowitt--Deser--Misner mass is no longer identical to its mass parameter. The behaviour of the tunnelling massive particles is investigated, and the emission rate at which massive particles tunnel across the event horizon of the black hole is calculated. The result is consistent with an underlying unitary theory, and takes the same functional form as that of mass-less particles.
