Influence of tubular initial conditions on two-particle correlations

TL;DR

This paper presents a unified model explaining near-side and away-side two-particle correlation structures in high-energy collisions, emphasizing the role of tubular initial conditions combined with hydrodynamics.

Contribution

It introduces a novel unified framework linking initial geometric configurations with observed correlation patterns in particle collisions.

Findings

The model successfully reproduces observed correlation structures.

Tubular initial conditions significantly influence correlation patterns.

Hydrodynamical expansion amplifies initial geometric effects.

Abstract

A unified description of the near-side and away-side structures observed in two-particle correlations as function of delta eta-delta phi is proposed for low to moderate transverse momentum. It is based on the combined effect of tubular initial conditions and hydrodynamical expansion.
