LoopFest XVIII

12 Aug 2019, 08:30 → 14 Aug 2019, 18:35 US/Central

Lecture Hall (IARC)

The Theoretical Physics department of Fermilab is pleased to welcome you to the LoopFest XVIII conference which will be held on August 12- August 14, 2019.

LoopFest provides a forum for discussing the latest results in precision quantum field theory and their applications to understanding experimental data at current and future colliders. The conference will consist of three days of plenary talks.

Topics include:

• The potential of the LHC and future colliders for precision measurements
• Progress in multi-loop and multi-leg calculations
• Interfacing fixed-order higher-order calculations with multi-purpose event generators
• Application of effective field theory techniques to precision calculations
• Prospects for improving PDFs for precision measurements

 

Local organizing committee:	Advisory Committee:
John Campbell	Lance Dixon
Marcela Carena	Frank Petriello
Walter Giele	Laura Reina
Stefan Hoeche	Doreen Wackeroth
Joshua Isaacson
Tobias Neumann

 

The conference will take place at the IARC lecture hall at Fermilab. For walking directions from Wilson Hall, see this map.
