I will present the first complete determination of the quark Collins-Soper kernel, which relates TMDs at different rapidity scales, using lattice QCD and including systematic control of quark mass, operator mixing, and discretization effects. Next-to-next-to-leading logarithmic matching is used to match lattice-calculable distributions to the corresponding TMDs. The continuum-extrapolated...

Regge limit in massless scattering amplitudes. In particular, all
the ingredients needed for the computation of the BFKL kernel at
NNLO have been determined in QCD, apart from the two-gluon
central emission vertex at one loop, which is known so far only
in maximally supersymmetric Yang-Mills theory. We present... -

Calculations in perturbative QCD suffer from large logarithms that appear at all orders in perturbation theory, endangering the perturbative description. In pursuit of precise predictions for cross sections, factorisation theorems have been established with the benefit to resum these large logarithms to all orders in perturbation theory, improving the predictive power of the theory. This...

We study scattering amplitudes and form factors in planar N=4 Super Yang-Mills theory and planar QCD in the limit where two pairs of gluons become collinear. We find that, when the virtualities of both collinear pairs are spacelike, the collinear factorisation of the amplitude involves a generalised splitting amplitude that correlates the two collinear directions. In N=4, we find that our...
