As a first step towards precise and differential predictions, we calculate the cross section for e+e− → 2 jets differential in the angularities eα and eβ. The logarithms of eα and eβ are jointly resummed to NNLL logarithmic accuracy, using the SCET+ framework we developed, and are matched with the NLO fixed-order prediction. We calculate the necessary ingredients, discuss scales and...

Transverse momentum dependent (TMD) parton densities at NLO from the Parton Branching method are obtained from fits to inclusive HERA DIS data. Collinear parton densities are also obtained using angular ordering constraints. The TMD densities are applied for predictions of processes at the LHC.

53. TMD splitting functions in kT factorization and TMD parton showers

In this talk we present two results: 1) We calculate the transverse momentum dependent gluon-to-gluon splitting function within kT-factorization, generalizing the framework employed in the calculation of the quark splitting functions in [1205.1759, 1511.08439, 1607.01507] and demonstrate at the same time the consistency of the extended formalism with previous results. While existing versions...
