Parton Showers and Resummation 2019

11 Jun 2019, 00:30 → 14 Jun 2019, 22:00 Europe/Zurich

Erwin Schrödinger Institut

The aim of the PSR workshop is to bring together the QCD communities involved in analytic resummations and parton shower event generators. The 2019 PSR workshop will focus on new developments both in analytic resummation and the development of parton shower algorithms, as well as their relation. We will also put emphasis on jet substructure techniques, as well as the physics of non-global observables and recent development on the handling of colour structureas well as Monte Carlo methods.

The core workshop will start on June 11, 2019 in the morning and willrun until June 13, late afternoon, with ample time for discussion. It will then be followed by a satellite meeting on hadronization models and hadronization corrections, both in analytic approaches as well as in Monte Carlo event generators.

June 11 - 13, 2019: Core Workshop

June 14, 2019: Satellite Meeting on Hadronization Models and Hadronization Corrections

Please note that June 10, 2019 is a public holiday in Austria. Thus the ESI will be closed on that day.
