 Title: Anisotropic jet momentum broadening and jet polarization

 Abstract: Heavy-ion collisions produce high-temperature QCD matter known as the quark-gluon plasma (QGP). Jets probe the QGP as they traverse the medium and undergo transverse momentum broadening. Recent work has shown that this momentum broadening is highly anisotropic in the early stages of heavy-ion collisions.
In the first half of this talk, we analyze in detail how anisotropic momentum broadening leads to net polarization of jet partons emitted in medium-induced bremsstrahlung. Jet polarization could therefore give a new way of measuring medium anisotropy.
In the second half of the talk, we provide our own calculation of jet broadening in an anisotropic, weakly-coupled quark-gluon plasma. A main result is that momentum broadening is substantially reduced at lower momenta compared with an equilibrium medium.
