Query: Quantum Critical Exponents for a Disordered Three-Dimensional Weyl Node   Three-dimensional Dirac and Weyl semimetals exhibit a disorder-induced
quantum phase transition between a semimetallic phase at weak disorder and a
diffusive-metallic phase at strong disorder. Despite considerable effort, both
numerically and analytically, the critical exponents $\nu$ and $z$ of this
phase transition are not known precisely. Here we report a numerical
calculation of the critical exponent $\nu=1.47\pm0.03$ using a minimal
single-Weyl node model and a finite-size scaling analysis of conductance. Our
high-precision numerical value for $\nu$ is incompatible with previous
numerical studies on tight-binding models and with one- and two-loop
calculations in an $\epsilon$-expansion scheme. We further obtain
$z=1.49\pm0.02$ from the scaling of the conductivity with chemical potential.
