# Event-by-event vortex rings in fixed-target p+Ar collisions

## TL;DR

This paper simulates vortex-ring structures in proton-argon collisions at high energy to predict their effects on Lambda hyperon polarization, offering insights for future experiments at the LHCb.

## Contribution

It introduces event-by-event simulations of vortex rings in p+Ar collisions and predicts their observable effects on hyperon polarization.

## Key findings

- Vortex-ring structures form during the collision evolution.
- Predicted polarization signals can be measured at LHCb.
- Simulations complement previous theoretical predictions.

## Abstract

We present event-by-event simulations for central asymmetric p+Ar collisions at $\sqrt{s_\mathrm{NN}} = 68$ GeV to investigate the formation and evolution of vortex-ring structures from the early-stage longitudinal flow velocity profile. Our predictions for their imprints on Lambda hyperon's polarization observables are complementary to those presented in Ref. [Phys.Rev.C 110 (2024) 5, 054908] and can be explored in the future fixed-target collisions at the Large Hadron Collider beauty (LHCb) experiment.
