  "abstract": "We study dc conductivity of a Weyl semimetal with uniaxial anisotropy (Fermi velocity ratio $\\xi= v_\\bot/v_\\parallel\\neq1$) considering the scattering of charge carriers by a wide class of impurity potentials, both short- and long-range. We obtain the ratio of transverse and longitudinal (with respect to the anisotropy axis) conductivities as a function of both $\\xi$ and temperature. We find that the transverse and longitudinal conductivities exhibit different temperature dependence in the case of short-range disorder. For general long-range disorder, the temperature dependence ($\\sim T^4$) of the conductivity turns out to be insensitive of the anisotropy in the limits of strong ($\\xi\\gg$ and $\\ll1$) and weak ($\\xi\\approx1$) anisotropy.",
