Neutrino stress tensor regularization in twodimensional spacetime
Abstract
The method of covariant pointsplitting is used to regularize the stress tensor for a massless spin 1/2 (neutrino) quantum field in an arbitrary twodimensional spacetime. A thermodynamic argument is used as a consistency check. The result shows that the physical part of the stress tensor is identical with that of the massless scalar field (in the absence of Casimirtype terms) even though the formally divergent expression is equal to the negative of the scalar case.
