IIHE Seminar Mar 29: Prof. Charlotte Van Hulse (Study of hadron structure in ultra-peripheral collisions at the LHC)
by Steven Lowette 29 Mar '24

29 Mar '24

Dear all, On Friday Mar 29 we will have an IIHE seminar from Prof. Charlotte Van Hulse: "Study of hadron structure in ultra-peripheral collisions at the LHC" at 14h30 in the Sacton seminar room (G.1.03) Abstract and short bio are below; the event's agenda can be found here: https://indico.iihe.ac.be/event/1919/ (note that via the top-left you can link the seminar agendas into your agenda, so you never miss one!) Kind regards, Steven. ----- Abstract: The study of exclusive processes in lepton-hadron interactions and in ultra-peripheral hadron-hadron collisions provides information on the three-dimensional distribution of quarks and gluons as a function of their longitudinal momentum and transverse position inside the hadron. Here, the longitudinal direction corresponds to the direction of the probe used to investigate the hadron. An introduction will be given as to how exclusive processes in ultra-peripheral hadron-hadron collisions provide access to the internal structure of the nucleon, and relevant experimental results will be discussed. Where applicable, parallels with measurements in lepton-hadron interactions will be highlighted. Bio: Charlotte Van Hulse is a professor at the University of Alcala in Spain. She did her PhD at Ghent University, where she studied exclusive and semi-inclusive QCD processes in lepton-hadron collisions at the HERMES experiment, at DESY, Hamburg. Subsequently she studied hadron formation in e+e- collisions, at the Belle experiment in Japan, and performed studies for a fixed target at ALICE. Nowadays she focuses on QCD (exclusive and semi-inclusive processes) at the LHCb experiment as well as feasibility/R&D studies for the future electron-ion collider at BNL, USA. -- Steven Lowette https://cern.ch/lowette/

IIHE Seminar Mar 22: Dr. James Howarth (Exploring quantum entanglement at hadron colliders using top quarks at the ATLAS experiment)

Dear all, On Friday Mar 22 we will have an IIHE seminar from Dr. James Howarth: "Exploring quantum entanglement at hadron colliders using top quarks at the ATLAS experiment" at 14h30 in the Sacton seminar room (G.1.03) Abstract and short bio are below; the event's agenda can be found here: https://indico.iihe.ac.be/event/1918/ Kind regards, Steven. ----- Abstract: ATLAS recently observed quantum entanglement in pairs of top quarks using 13 TeV data, the first time that entanglement has been observed in fundamental quarks and at the highest ever energy scales. In this seminar I will explain how this ground breaking measurement was achieved, how it highlights limitations in our current state-of-the-art Monte Carlo simulations, and the implications of the result in the wider context of quantum information. I will also explain what direction this exciting new field of study at collider experiments might take and highlight new opportunities for collaborations between quantum information and collider physics. Bio: Dr James (Jay) Howarth is a Lecturer at the University of Glasgow and Royal Society University Research Fellow. He obtained his PhD at the University of Manchester in 2013, followed by a research fellowship at DESY and a postdoctoral research position at the University of Manchester. His research focuses on top quark physics in general, particularly on the properties of top quarks at hadron colliders and is a member of the ATLAS collaboration. -- Steven Lowette https://cern.ch/lowette/

IIHE Seminar Mar 7: Dr. Richard Ruiz (Vector Boson Scattering: Status and Prospects for the Large Hadron Collider and Beyond)
by Steven Lowette 07 Mar '24

07 Mar '24

Dear all, On Thursday Mar 7 we will have an IIHE seminar from Dr. Richard Ruiz: "Vector Boson Scattering: Status and Prospects for the Large Hadron Collider and Beyond" at 15h00 in the Sacton seminar room (G.1.03) Note the *unusual day and time* to accommodate the speaker's travel constraints. Abstract and short bio are below; the event's agenda can be found here: https://indico.iihe.ac.be/event/1917/ Kind regards, Steven. ----- Abstract: The scattering of electroweak bosons at TeV-scale super colliders is a powerful mechanism that probes spin and charge configurations inaccessible to quark and gluon scattering. Electroweak vector boson scattering (VBS) processes therefore give unique insights into the Standard Model's gauge and Higgs sectors, as well as into models of new physics. In this talk, we review experimental results and ongoing theoretical developments of VBS at the Large Hadron Collider, its high luminosity upgrade, and its potential successors. Short Bio: Richard Ruiz is a specialist in collider physics, and particularly searches for violations of lepton symmetries using electroweak boson scattering as a probe of new physics at the Large Hadron Collider. After earning his PhD at the University of Pittsburgh in 2015 on the topic "hadron collider tests of neutrino mass models", Richard moved to Durham University's Institute for Particle Physics Phenomenology in the UK. In 2018, he moved to the Universite Catholique de Louvain's Center for Cosmology and Particle Physics Phenomenology and finally joined the Institute for Nuclear Physics Polish Academy of Science (IFJ PAN) in Krakow, in 2020. He is credited in his habilitation with "influential theoretical contributions to understanding and using vector boson scattering as a probe of new physics at the LHC, its high-luminosity upgrade, and future high-energy collider experiments," which is the topic of the talk. Despite being a theorist investigating fundamental aspects of collider theory, Richard is heavily involved in experimental activities at CERN due to his work on developing user-friendly simulation tools. -- Steven Lowette https://cern.ch/lowette/
