Anisotropic Flow of Strange Hadrons in Relativistic Heavy-ion Collisions Measured with HADES

Key Points

This research aims to analyze the anisotropic flow of strange hadrons produced in heavy-ion collisions at specific energy levels.
Analyzed data from Ag+Ag collisions at 1.58 GeV per nucleon.
Expressed anisotropic flow using Fourier coefficients of 1st and 2nd order.
Focused on directed flow due to statistical limitations.
The directed flow of K+ shows a negative slope in the low-pT region, unlike protons.
The directed flow slope of Λ hadrons aligns with protons, regardless of momentum.

Abstract

In this contribution, the ongoing analysis of the anisotropic flow of strange hadrons (\ (K^ \), \ (\) ) emitted from the Ag+Ag collisions at a beam kinetic energy of 1. 58 GeV per nucleon is presented. The anisotropic flow is expressed with the Fourier coefficients of the \ (1^ st\) and \ (2^ nd\) order, corresponding to the directed and elliptic flow, respectively. However, only the \ (v₁\) distribution is shown due to statistical limitations. The directed flow of \ (K^+\) has a negative slope in the low-\ (p ₓ\) region, opposite to protons, while the \ (v₁\) slope of \ (\) is similar to that of the protons regardless of momentum.
