Top Quark Physics at the Precision Frontier

15 May 2019, 08:00 → 17 May 2019, 18:30 America/Chicago

Curia II (WH2SW) (Fermilab, Wilson Hall)

Andreas Jung (Purdue University (US)), Reinhard Schwienhorst (Michigan State University (US))

The workshop aims at discussing progress made so far in understanding the top quark sector. With the end of LHC Run 2, we will have collected tens of millions of top quark events. This opens a new precision frontier with top quarks, which is the focus of the workshop, providing a forum for detailed discussion on how to address new challenges with top cross-section, mass, properties measurements and theoretical predictions.

We would really appreciate if you could fill the following participants feedback form whether you attended this workshop live or offline, it will help us improve the LPC events offering:
