TL;DR

This paper introduces a soliton-based nonlinear Lorentz-invariant model to describe azimuthal-anisotropic elliptical flows in quark-gluon plasma and hadron jets, highlighting differences from hydrodynamic models and proposing a photon flow hypothesis.

Contribution

It develops a novel soliton model with negative acceleration to explain elliptical flows, offering an alternative to traditional hydrodynamic approaches.

Findings

Localized solutions mimic elliptical flow formation

Elliptic flow exhibits significant negative acceleration

Proposes photon flow as braking radiation of QGP

Abstract

The paper presents a system of nonlinear Lorentz-invariant equations. The behavior of their localized solutions is analogous to the processes of formation of azimuthal-anisotropic elliptical flows of quark-gluon plasma and hadron jets. In contrast to the hydrodynamic models of an ideal fluid, the elliptic flow in this model has a significant negative acceleration. The presence of the negative acceleration allows us to propose a hypothesis about the direct elliptic flow of photons as braking radiation QGP.
