Abstract
We investigate the critical behavior of the gauge
glass model for the vortex glass transition in three-dimensional
superconductors,
including screening of the interaction between vortices.
A Monte Carlo study of the linear resistivity and
a scaling analysis of current--voltage characteristics
indicates that screening destroys the finite--temperature
transition found earlier when screening was neglected. The
correlation length exponent at the resulting zero temperature transition
is found to be $\nu=1.05 \pm 0.1$.
