NNLL fit of the transverse-momentum-dependent distribution of unpolarised gluons to LHCb data on -pair production
D. Boer, J. Bor, A. C. Serri +4
We perform the first fit of the unpolarised gluon transverse-momentum-dependent distribution up to next-to-next-to-leading-logarithmic accuracy to the double-differential d…

Modeling the TMD shape function in electroproduction
Miguel G. Echevarria, Raj Kishore, Samuel F. Romera
The next-to-leading order hard function for quarkonium electroproduction is calculated within the framework of transverse-momentum-dependent (TMD) factorization in the low-transver…

Factorization for leptoproduction at small transverse momentum
Miguel G. Echevarria, Samuel F. Romera, Pieter Taels
Nonrelativistic Quantum Chromodynamics (NRQCD) breaks down in the region of low transverse momentum, where the transverse momentum of the produced quarkonium state is sensitive to…
