Elliptic and triangular flows in dAu collisions at 200 GeV in the fusing color string model

TL;DR

This paper investigates elliptic and triangular flows in d-Au and p-Au collisions at 200 GeV using the color string model with fusion and percolation, successfully reproducing some experimental observations.

Contribution

It applies the color string model with fusion and percolation to study flow phenomena in small collision systems, providing a theoretical explanation for observed flow ordering.

Findings

Reproduces the experimental flow ordering $v_n(d-Au)>v_n(p-Au)$ for central collisions.

Satisfactorily matches the measured elliptic flow $v_2$ at central collisions.

Overestimates the triangular flow $v_3$ compared to experimental data.

Abstract

In the color string picture with fusion and percolation the elliptic and triangular flows are studied for p-Au and d-Au collisions at 200 GeV. The ordering $v_n(d-Au)>v_n(p-Au)$ observed experimentally for central collisions is reproduced.The calculated elliptic flow $v_2$ at central collisions agrees satisfactorily with thedata. The triangular flow $v_3$ is found to be greater than the experimental values, similar to the resultsobtained in the approach based on the Color Glass Condensate initial conditions with subsequenthydrodynamical evolution.
