Resummation, Evolution, Factorization 2020
On line
Resummation, Evolution, Factorization 2020 will exceptionally take place on line. Registration and abstract submission is now open (submission deadline Oct. 20th) -- please use the link below.
This workshop is the 7th edition in a series of workshops aiming to bring together experts who deal with high-energy hadronic processes where the transverse momentum of the scattering partons plays a relevant role. This includes researchers of different communities specialized in, e.g., nucleon structure, transverse-momentum-dependent functions, small-x physics, jet physics, heavy-quark production, multi-parton interactions, etc.
Factorization theorems and resummation of large logarithms through evolution equations are key concepts for all these communities, which address overlapping physical phenomena with however different languages, calling for mutual understanding.
Indeed, this series of workshops aims at bridging the gap among them, to promote development and potential synergies, in view of the wealth of data taken at facilities like the LHC, RHIC or JLab, and future planned ones like the EIC.
