35. TMD Factorization and Resummation at NLO+NLP

Dr John Terry (LANL)

27/03/2023, 16:00

In this talk, I'll present our results on transverse momentum dependent factorization and resummation at sub-leading power. I'll discuss the explicit formalism for calculating the hard, soft and collinear contributions to the sub-leading cross sections at one loop. I'll demonstrate that at this perturbative order, the leading and sub-leading power distributions mix, which gives rise to...

36. Sudakov logarithms from double lightcone OPE

Energy-Eenrgy Correlator exhibits Sudakov logarithms in the back-to-back limit. At leading power, these logarithms can be resummed to all orders using TMD factorization method. However, going beyond the leading power remains challenging in this approach. In this talk I will introduce a novel approach to resum Sudakov logarithms in EEC, both at leading and subleading power. I will show that the...

9. Gauge invariance of radiative jet functions

June-Haak Ee (Fudan university)

In subleading powers of SCET, the Lagrangian contains couplings between soft quarks and hard-collinear quarks. Matrix elements of the hard-collinear part of these couplings are radiative jet functions. Although the radiative jet functions are constructed to contain hard-collinear modes, we find that, in order to render the radiative jet functions gauge invariant, it is necessary, in general,...
