Resummation, Evolution, Factorization 2024

14 oct. 2024, 09:00 → 18 oct. 2024, 17:00 Europe/Paris

Amphi Claude Bloch (Institut de Physique Théorique)

 

***  REGISTRATION IS NOW CLOSED ***

 

REF 2024 is the 11th edition in the series of workshops on Resummation, Evolution and Factorization. 

The workshop brings together specialists in different areas, from effective field theory to lattice to QCD factorization methods. The main focus will be on transverse momentum dependent distributions (TMDs) and their connection with Monte Carlo event generators, as well as on the experimental measurements aimed at extracting information on TMDs at present and future colliders. The interplay between the factorization theorems, resummation of large logarithms, and the corresponding evolution equations are crucial for higher precision calculations, necessary not only for understanding the data recorded by past and present facilities, such as the LHC, HERA and Belle, but especially for future experiments, such as HL-LHC, EIC, and FCC.

The 2024 edition of REF will be hosted at the Institut de Physique Théorique, in Saclay (France), from October 14th to 18th, 2024. To facilitate travel for those in Europe, the workshop will start on Monday at 14:00 and end on Friday at the end of the morning session (a lunch buffet will be served after the session).

The registration fee is 170 euros per participant without the workshop dinner  (includes a welcome reception, coffee breaks, and lunches) and 250 euros with the workshop dinner.
