Kickoff meeting - GDR-QCD / WG1 : Simple and Multiple Interactions between Partons

21 juin 2021, 09:00 → 23 juin 2021, 14:00 Europe/Paris

Cédric Lorcé (Ecole Politechnique), Dominique Marchand (IPN Orsay, CNRS/IN2P3 and University Paris-Sud), Zaida Conesa del Valle (IPN Orsay)

This is the kickoff meeting of our GDR-QCD working group. It is open to all GDR-QCD members. The idea is to gather people intested in "Simple and Multiple Interactions between Partons", and to identify central questions that can be addressed in the next four years.

The format of the meeting will be two or three half-days (likely the morning) from June 21 to June 23. The meeting will be online with presentations and discussions.

Please register and submit your proposal for an oral contribution before May 31st on the website (see tab on the left).
