These corrections are related to curvature-squared corrections in the corresponding gravity dual. The results are compared with the dual gauge theory. It is shown that curvature-squared corrections affect the drag force. It is shown that corrections to the drag force depend on the velocity of the heavy quark. The diffusion coefficient of non-relativistic heavy quarks is calculated from the drag force. In addition, we also calculate the drag force on a moving heavy quark in the Gauss-Bonnet background.12 pages, 1 figure, published version in JHEPHigh Energy Physics - TheoryHigh Energy Physics - Phenomenology$R^2$ curvature-squared corrections on drag forcetext
