abstract
We examine the formation of vortical "smoke rings" as a result of thermalization of energy lost by a jet. We simulate the formation and evolution of these rings using hydrodynamics and define an observable that allows to probe this phenomenon experimentally. We argue that observation of vorticity associated with jets would be an experimental confirmation of the thermalization of the energy lost by quenched jets, and also a probe of shear viscosity.

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.
