Vacuum polarization of a massless spinor field in global monopole spacetime

We calculate the renormalized vacuum average of the energy-momentum tensor of a massless left-handed spinor field in the pointlike global monopole spacetime using point-separation approach. The general structure of the vacuum average of the energy-momentum tensor is obtained and expressed in terms of a $〈{T}_{0}^{0}{〉}^{\mathrm{ren}}$ component, the explicit form of which is analyzed in great detail for an arbitrary solid angle deficit.
