Query: Theory of the Resistive Transition in Overdoped $Tl_2Ba_2CuO_{6+x}$:
  Implications for the angular dependence of the quasiparticle scattering rate
  in High-$T_c$ superconductors   We show that recent measurements of the magnetic field dependence of the
magnetization, specific heat and resistivity of overdoped $T_c \sim 17K$
$Tl_{2}Ba_{2}CuO_{6+\delta}$ in the vicinity of the superconducting $H_{c2}$
imply that the vortex viscosity is anomalously small and that the material
studied is inhomogeneous with small, a few hundred $\AA$, regions in which the
local $T_{c}$ is much higher than the bulk $T_{c}$. The anomalously small
vortex viscosity can be derived from a microscopic model in which the
quasiparticle lifetime varies dramatically around the Fermi surface, being
small everywhere except along the zone diagonal (``cold spot''). We propose
experimental tests of our results.
