The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

The conditions for the development of a Kelvin-Helmholtz Instability (KHI) for the Quark-gluon Plasma (QGP) flow in a peripheral heavy-ion collision is investigated. The projectile and target side particles are separated by an energetically motivated hypothetical surface, characterized with a phenomenological surface tension. In such a view, a classical potential flow approximation is considered and the onset of the KHI is studied. The growth rate of the instability is computed as function of phenomenological parameters characteristic for the QGP fluid: viscosity, surface tension and flow layer thickness.

The paper

Original abstract

The conditions for the development of a Kelvin-Helmholtz Instability (KHI) for the Quark-gluon Plasma (QGP) flow in a peripheral heavy-ion collision is investigated. The projectile and target side particles are separated by an energetically motivated hypothetical surface, characterized with a phenomenological surface tension. In such a view, a classical potential flow approximation is considered and the onset of the KHI is studied. The growth rate of the instability is computed as function of phenomenological parameters characteristic for the QGP fluid: viscosity, surface tension and flow layer thickness.

In [ref] we argued that the problem here is that the computations in [ref] (which was concerned with a different application, to cosmological magnetic fields) neglected an important physical effect: the fact that these collisions involve not just large magnetic fields, but also large angular momentum densities, as predicted in [ref] , and possibly observed by the STAR collaboration [ref] .

The holographic approach is therefore complementary to the classical methods used in [ref] , in the sense that it describes the situation everywhere in the fluid except near to the zone where the Kelvin–Helmholtz instability is expected to arise.

This angular momentum can be associated with either rotation [ref] (see [ref] for the most recent developments) or shear [ref] ; the latter will be our concern here.

Inverse Magnetic/Shear Catalysis · Section · 0.83
It has long been predicted [ref] that peripheral heavy-ion collisions, as studied in the RHIC and LHC facilities, will generically give rise to a Quark-Gluon Plasma (QGP) with a very large vorticity.

Jet Quenching in The Most Vortical Fluid: A Holographic Approach · Section · 0.80
It is thought [ref] that the angular momentum transferred to the QGP in a peripheral collision can take the form either of rotation or of internal shearing; this depends on physical parameters such as the viscosity of the specific plasma being examined.
