Top-Quark Mass Scheme Uncertainties in Higgs Boson Pair Production via Gluon Fusion

We investigate theoretical uncertainties arising from the choice of the top-quark mass scheme in Higgs boson pair production via gluon fusion. First, we implement the resummation of the top-quark mass logarithms obtained for the $gg\to HH$ amplitude at high energy and study its phenomenological impact on cross sections...

Third-Order Logarithmic Resummation for Jet-Vetoed Higgs Production

Jet vetoes are central to precision measurements of Higgs-boson properties at the Large Hadron Collider, where they are used to suppress backgrounds containing hard QCD radiation. We present the first prediction for the Higgs jet-vetoed cross section at the third logarithmic order in QCD, consistently combining the nex...

RADIATIVE CORRECTIONS IN BOUND STATES ∗

Next-to-leading power endpoint DIS and PDF factorization

We study deep-inelastic scattering (DIS) in the threshold region $x\to 1$ beyond leading power in $1-x$ at leading twist. In the framework of position-space soft-collinear effective theory, we derive a factorization theorem for the off-diagonal parton-scattering channel, which starts at next-to-leading power (NLP). The...

Three-loop rapidity anomalous dimension for jet-veto cross sections

We present the first calculation of the third-order corrections to the rapidity anomalous dimension for jet-veto cross sections. This is a crucial ingredient for the resummation of these scattering observables in key processes such as colour-singlet and heavy-quark-pair production at hadron colliders. More precisely, o...
