abstract
We present event-by-event simulations for central asymmetric light+heavy and Au+Au collisions to investigate the formation and evolution of vortex-ring structures in the longitudinal flow velocity profile. The production-plane polarization of $\Lambda$ hyperons, defined w.r.t. the $\Lambda$ momentum and the beam, can track the "vortex-ring" feature in the event, a characteristic vortical structure generated by longitudinal flow gradients. We make comprehensive model predictions for the rapidity-dependent vortex-ring observables for different collision system sizes at $\sqrt{s_\mathrm{NN}} = 200$ and 72 GeV. Our predictions at the latter energy can be explored in the future LHCb fixed-target experiment at the Large Hadron Collider.

Event-by-event vortex rings in fixed-target p+Ar collisions
Hydrodynamic simulations predict lambda polarization in p+Ar collisions that is six times larger for strong early longitudinal flow than for Bjorken flow, with an anti-lambda sign flip at weak flow, testable at LHCb SMOG.
