Query: Coulomb scattering in plasma revised   A closed expression for the momentum evolution of a test particle in
weakly-coupled plasma is derived, starting from quantum many particle theory.
The particle scatters from charge fluctuations in the plasma rather than in a
sequence of independent binary collisions. Contrary to general belief, Bohr's
(rather than Bethe's) Coulomb logarithm is the relevant one in most plasma
applications. A power-law tail in the distribution function is confirmed by
molecular dynamics simulation.
