# Spiraling String in Gauss-Bonnet Geometry

## TL;DR

This paper investigates a spiraling string in Gauss-Bonnet geometry to understand energy loss mechanisms of a rotating heavy particle in a hot plasma at finite coupling, revealing how finite coupling affects energy loss channels.

## Contribution

It introduces a novel holographic model of a spiraling string in Gauss-Bonnet geometry to analyze energy loss in strongly coupled plasma, highlighting the effects of finite coupling.

## Key findings

- Finite coupling shifts energy loss curves compared to infinite coupling.
- The crossover between drag force dominance and radiation dominance is unaffected by Gauss-Bonnet coupling.
- The model provides new insights into energy loss channels in strongly coupled theories.

## Abstract

In this paper, we consider a spiraling string falling in the bulk with Gauss$-$Bonnet 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 Gauss$-$Bonnet coupling.
