[Seminar] Abdennacer Hamdi (GSI), July 7th, 2020.

We are delighted to announce that we will have an Astroparticle Physics Seminar talk given by Abdennacer Hamdi from GSI on July 6th. Please join and welcome his talk together.

This seminar will be held virtually via ZOOM teleconference due to the recommended social distancing in Korea over the current coronavirus situation. Please contact Prof. Rott to get the detail connection information beforehand to join the seminar.


Title: Search for exotic mesons in photoproduction at GlueX [Presentation_slides]

Speaker: Abdennacer Hamdi (GSI)

Date & Time: Tuesday, July 7th, 2020. 16:00 KST (9:00 CEST)

Place: Virtual (via ZOOM)

Quantum Chromodynamics (QCD) is the theory that describes how hadrons are built from quarks and gluons via the strong interaction. Many predictions have been observed, but many others remain under experimental investigation. Of particular interest is how gluonic excitations give rise to exotic states. One class of such states are hybrid mesons that are predicted by theoretical models and Lattice QCD calculations. Search for and understanding the nature of these states is one of the primary physics goal of the GlueX experiment at the CEBAF accelerator at Jefferson Lab in the US. I will give an overview on the experiment, and present the first results on the search for a hybrid meson candidate, namely the Y (2175).
