Impact of low-x resummation on QCD analysis of HERA data [PDF]
European Physical Journal C: Particles and Fields, 2018 Fits to the final combined HERA deep-inelastic scattering cross-section data within the conventional DGLAP framework of QCD have shown some tension at low x and low $$Q^2$$ Q2 .

Momentum-space resummation for transverse observables and the Higgs p⊥ at N3LL+NNLO
Journal of High Energy Physics, 2018 We present an approach to the momentum-space resummation of global, recursively infrared and collinear safe observables that can vanish away from the Sudakov region.

PhysicsScaling of the cost-functional and its violations are discussed with regard to their application to the summation of asymptotic truncated expansions. A new family of cost-functionals dependent only on amplitudes is considered, allowing for a continuous ...

High energy resummation of jet observables
Journal of High Energy Physics, 2017 In this paper we investigate the extension of high energy resummation at LLx accuracy to jet observables. In particular, we present the high energy resummed expression of the transverse momentum distribution of the outgoing parton in the general partonic

Improved thermal resummation for multi-field potentials
Journal of High Energy PhysicsThe resummation of large thermal corrections to the effective potential is mandatory for the accurate prediction of phase transitions. We discuss the accuracy of different prescriptions to perform this resummation at the one- and two-loop level and point

Event-based transverse momentum resummation. [PDF]
Eur Phys J C Part Fields, 2019 We have developed a framework for automated transverse momentum resummation for arbitrary electroweak final states based on reweighting tree-level events.

On the IR-resummation in the EFTofLSS [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 We propose a simplification for the IR-resummation scheme of Senatore and Zaldarriaga, and also include its next-to-leading order corrections coming from the tree-level three-point function of the long displacement field. First we show that the new simplified formula shares the same properties of the resummation of Senatore and Zaldarriaga.

Fiducial qT resummation of color-singlet processes at N3LL+NNLO [PDF]
, 2021 We present a framework for qT resummation at N3LL+NNLO accuracy for arbitrary color-singlet processes based on a factorization theorem in SCET. Our implemen- tation CuTe-MCFM is fully differential in the Born kinematics and matches to large-qT fixed ...

Soft Anomalous Dimensions and Resummation in QCD
Universe, 2020 I discuss and review soft anomalous dimensions in QCD that describe soft-gluon threshold resummation for a wide range of hard-scattering processes. The factorization properties of the cross section in moment space and renormalization-group evolution are ...
