Spiraling String in Gauss-Bonnet Geometry
arXiv:1906.11621 · doi:10.1016/j.physletb.2019.135090
Abstract
In this paper, we consider a spiraling string falling in the bulk with GaussBonnet geometry that is holographically dual to a heavy particle rotating through a hot plasma at finite coupling. One finds such interesting simple problem provides a novel perspective on different channels of the energy loss in the corresponding strongly coupled theory. Depends on the sign of the coupling, one observes that the influence of finite coupling on total energy loss and contribution of drag force and radiation channels appears as a shift on curves with respect to the plasma with infinite coupling. Also we found that crossover between regime in which drag force contribution is predominant to regime in which energy loss is due to radiation, does not depend on the GaussBonnet coupling.
