Jet quenching in the glasma phase: medium-induced radiation
João Barata, Sigtryggur Hauksson, Xoán Mayo López +1
Inspired by the recent considerations of parton momentum broadening in the glasma phase, we study the medium-induced soft gluon radiation of jet partons at early times in heavy-ion…
Isotropization of a longitudinally expanding system of scalar fields in the 2PI formalism
François Gelis, Sigtryggur Hauksson
Motivated by isotropization of QCD matter in the initial stages of heavy-ion collisions, we consider a system of scalar fields that undergoes a boost invariant longitudinal expansi…
TMD factorisation for diffractive jets in photon-nucleus interactions
S. Hauksson, E. Iancu, A. H. Mueller +2
Using the colour dipole picture and the colour glass condensate effective theory, we study the diffractive production of two or three jets via coherent photon-nucleus interactions…
Study of a longitudinally expanding plasma with the 2PI effective action
François Gelis, Sigtryggur Hauksson
A central question in heavy-ion collisions is how the initial far-from-equilibrium medium evolves and thermalizes while it undergoes a rapid longitudinal expansion. In this work we…
Jet polarisation in an anisotropic medium
Sigtryggur Hauksson, Edmond Iancu
We study the evolution of an energetic jet which propagates in an anisotropic quark-gluon plasma, as created in the intermediate stages of ultrarelativistic heavy-ion collisions. W…
The momentum broadening of energetic partons in an anisotropic plasma
Sigtryggur Hauksson, Sangyong Jeon, Charles Gale
The quark-gluon plasma produced in heavy-ion collisions is anisotropic throughout its evolution. This anisotropy changes the physics of jet-medium interaction, making it dependent…
Probes of the quark-gluon plasma and plasma instabilities
Sigtryggur Hauksson, Sangyong Jeon, Charles Gale
Penetrating probes in heavy-ion collisions, like jets and photons, are sensitive to the transport coefficients of the produced quark-gluon plasma, such as shear and bulk viscosity.…
Hard probes of non-equilibrium quark-gluon plasma
Sigtryggur Hauksson, Sangyong Jeon, Charles Gale
Jets and photons could play an important role in finding the transport coefficients of the quark-gluon plasma. To this end we analyze their interaction with a non-equilibrium quark…
