# Toward the description of fluid dynamical fluctuations in heavy-ion collisions

## TL;DR

This paper explores how fluid dynamical fluctuations influence relativistic viscous fluid dynamics in heavy-ion collisions, focusing on nonlinear interactions and cutoff effects in a 3+1 dimensional framework.

## Contribution

It introduces the inclusion of fluid dynamical fluctuations into relativistic viscous fluid dynamics models for heavy-ion collisions, highlighting nonlinear and cutoff effects.

## Key findings

- Fluctuations significantly affect fluid dynamics in heavy-ion collisions.
- Nonlinear interactions modify fluctuation behavior.
- Cutoff dependence impacts the modeling of fluctuations.

## Abstract

In this talk we present results obtained when fluid dynamical fluctuations are included in relativistic $3+1$ dimensional viscous fluid dynamics. We discuss effects of the interactions of fluctuations due to nonlinearities and the cutoff dependence.
