Jets and their substructure from LHC data

On-line only (CERN)

Description

This CERN-TH workshop will be held virtually on ZOOM between 31 May - 4 Jun. We invite you to register through the menu item on the left. The workshop will involve a mixed audience of experimentalists and theorists, with a particular emphasis on phenomenology and the open challenges in jet physics at the LHC. The main programme will take place in the early afternoon and topical discussion sessions will be organised both in the morning and in the late afternoon. In order to foster lively discussions, we wish to accommodate 2-3 short talks (10-15mins) in each discussion session. We encourage participants, especially young researchers, to submit their abstract using the form via the "Call for Abstracts" menu on the left.
