Abstract
We calculate the renormalized vacuum average of the energy-momentum tensor of 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 <T00>ren component, explicit form of which is analyzed in great details for arbitrary solid angle deficit.
