    Marta Verwey (UU) – Nikhef colloquium
    Titel: Parton shower modifications in a hot QCD medium

    Abstract:
    In collisions between relativistically accelerated lead ions a dense medium is formed: the quark-gluon plasma (QGP). These type of collisions are used to study matter in phases where quarks and gluons are no more confined into hadrons and where chiral symmetry is restored. Hard scattered partons are used to map out the properties of the QGP. As a parton passes through the QCD medium, induced energy loss from elastic and radiative interactions leads to a modification of the parton shower; this modification is used to deduce medium properties.

    In this talk, jet quenching calculations and phenomenology are confronted with measurements in heavy-ion collisions at the Large Hadron Collider. In particular the use of jet substructures to study specific properties of hot QCD matter will be presented.

  • Location:

    The Nikhef colloquium will take place in room Z011 at CWI/Nikhef.
    For those who want to follow the colloquium online, a webcast is available.

    The program consists of a Nikhef colloquium in the morning, which will be a hybrid event: It can be attended in person as well as online via a webcast.

    The afternoon session will be virtual only, in a correspondingly slimmed-down format: three presentations of 20 minutes in which new faculty/postdocs introduce themselves.

  • Schedule:

    The schedule is as follows:

    11.00 -12.00 Nikhef Colloquium – Marta Verwey (UU) – Titel: Parton shower modifications in a hot QCD medium

    14:00 -14:20 Ema Dimastrogiovanni (RUG) – Gravitational waves from inflation

    14:20 -14:40 Jay Armas (UvA) – Causality and stability issues in magnetohydrodynamics

    14:40 -15:00 Sander Mooij (EPFL, Nikhef) – On naturalness and UV infinities in QFT
