Harsh Shah (Lund University): A Spatially Constrained QCD Colour Reconnection in Pythia8/Angantyr Model for Heavy-ion Collisions

Friday 23 Jun 2023, 10:15 → 11:00 Europe/Warsaw

Abstract:

I will provide an overview of the Angantyr model for heavy-ion collisions, which is a direct extrapolation of Pythia event generator. The Angantyr model does not consider QGP creation in its heavy-ion events simulation. I will further talk about the latest work of introducing a spatial constraint in the QCD-inspired colour reconnection model for pp events in Pythia, which we extend for pA and AA collisions in the Angnatyr model. This new update allows a more inclusive treatment of the sub-collisions in the heavy-ion events. I will show results like multiplicity distributions and baryon-to-meson rations from the Pythia/Angantyr model. I will conclude by sharing some potential ideas which may provide alternative explanations about the underlying physics of some of the observables which are considered results of the QGP formation.

Important: This seminar is held in building D-11 room 104.
