Search for a Ridge Structure Origin with Shower Broadening and Jet Quenching

TL;DR

This paper explores how jet and shower parton broadening caused by strong colour fields can produce ridge-like structures in high transverse momentum particle correlations, highlighting the effects of anisotropic momentum broadening.

Contribution

It introduces a model where anisotropic momentum broadening leads to ridge structures in particle correlations, providing insights into the origin of such features in high-energy collisions.

Findings

Ridge-like structures emerge with anisotropic momentum broadening.

The model overestimates the ratio of peak to pedestal yields.

Jet broadening influences two-hadron correlation patterns.

Abstract

We investigate the role of jet and shower parton broadening by the strong colour field in the $\Delta\eta$-$\Delta\phi$ correlation of high $p_T$ particles. When anisotropic momentum broadening ($\Delta p_z > \Delta p_T$) is given to jet and shower partons in the initial stage, a ridge-like structure is found to appear in the two hadron correlation. The ratio of the peak to the pedestal yield is overestimated.
