      abstract     = {We estimate the momentum diffusion coefficient of a heavy
                      quark within a pure SU(3) plasma at a temperature of about
                      1.5Tc. Large-scale Monte Carlo simulations on a series of
                      lattices extending up to 1923×48 permit us to carry out a
                      continuum extrapolation of the so-called color-electric
                      imaginary-time correlator. The extrapolated correlator is
                      analyzed with the help of theoretically motivated models for
                      the corresponding spectral function. Evidence for a nonzero
                      transport coefficient is found and, incorporating systematic
                      uncertainties reflecting model assumptions, we obtain
                      κ=(1.8–3.4)T3. This implies that the “drag
                      coefficient,” characterizing the time scale at which heavy
                      quarks adjust to hydrodynamic flow, is
                      η−1D=(1.8–3.4)(Tc/T)2(M/1.5  GeV)  fm/c, where
                      M is the heavy quark kinetic mass. The results apply to
                      bottom and, with somewhat larger systematic uncertainties,
                      to charm quarks.},
