Stable perturbative predictions for isolated photon production with a jet pair at large $ {m}_{j_1{j}_2} $A bstract: We present the first calculation of the high-energy corrections to the process of isolated photon production in association with two jets. These corrections both stabilise the perturbative behaviour in $$ {m}_{j_1{j}_2} $$ and lead to a significantly improved description of data from a recent ATLAS measurement.- 23 October 2025

Progress towards High-energy logarithmic resummation at full next-to-leading logarithmic accuracy
We discuss briefly recent progress towards a method for obtaining full next-to-leading high-energy logarithmic accuracy for processes while maintaining analytic properties such as crossing symmetry and gauge-invariance of the amplitudes. The additional analytic requirements help constrain the behaviour of the amplitudes away from the asymptotic limit. This aids the accuracy of the predictions beyond the logarithmic precision. Furthermore, the framework ensures full energy and momentum conservation necessary for next-to-leading logarithmic precision not just of the amplitudes but also of the cross sections.

Exploring High-Purity Multiparton Scattering at Hadron Colliders
Multiparton interactions are a fascinating phenomenon that occur in almost every high-energy hadron-hadron collision yet are remarkably difficult to study quantitatively. In this Letter, we present a strategy to optimally disentangle multiparton interactions from the primary scattering in a collision. That strategy enables probes of multiparton interactions that are significantly beyond the state of the art, including their characteristic momentum scale, the interconnection between primary and secondary scatters, and the pattern of three and potentially even more simultaneous hard scatterings. This opens a path to powerful new constraints on multiparton interactions for LHC phenomenology and to the investigation of their rich field-theoretical structure.

High-Energy and Soft-Collinear Resummation for Jet Production at the LHC
We discuss the progress in the development of HEJ+Pythia framework, which accounts for both the high-energy, and soft-collinear logarithms as implemented in the High Energy Jets partonic Monte Carlo, and Pythia8, respectively. The method to combine the two all-order descriptions point-by-point in phase-space is presented, and we verify the validity of the framework through comparisons of predictions produced with this merging scheme and ATLAS data.

Efficient negative-weight elimination in large high-multiplicity Monte Carlo event samples
We demonstrate that cell resampling can eliminate the bulk of negative event weights in large event samples of high multiplicity processes without discernible loss of accuracy in the predicted observables. The application of cell resampling to much larger data sets and higher multiplicity processes such as vector boson production with up to five jets has been made possible by improvements in the method paired with drastic enhancement of the computational efficiency of the implementation.

High energy resummed predictions for the production of a Higgs boson with at least one jet
We present all-order predictions for Higgs boson production plus at least one jet which are accurate to leading logarithm in $$ \hat{s}/{\left|{p}_{\perp}\right|}^2 $$ . Our calculation includes full top and bottom quark mass dependence at all orders in the logarithmic part, and to highest available order in the tree-level matching. The calculation is implemented in the framework of High Energy Jets (HEJ). This is the first cross section calculated with log( $$ \hat{s} $$ ) resummation and matched to fixed order for a process requiring just one jet, and our results also extend the region of resummation for processes with two jets or more. This is possible because the resummation is performed explicitly in phase space. We compare the results of our new calculation to LHC data and to next-to-leading order predictions and find a numerically significant impact of the logarithmic corrections in the shape of key distributions, which remains after normalisation of the cross section.- 1 March 2023

Logarithmic corrections to the QCD component of same-sign -pair production for vector boson scattering studiesWe present the results of the first calculation of the logarithmic corrections to the QCD contribution to same-sign -pair production, , for same-sign charged leptons. This includes all leading logarithmic contributions which scale as . This process is important for the study of electroweak couplings and hence the QCD contributions are usually suppressed through a choice of vector boson scattering cuts. These select regions of phase space where logarithms in are enhanced. While the logarithmic corrections lead to a small change for the cross sections, several distributions relevant for experimental studies are affected more significantly.- 7 December 2021

Combined subleading high-energy logarithms and NLO accuracy for W production in association with multiple jets
Large logarithmic corrections in $$ \hat{s}/{p}_t^2 $$ lead to substantial variations in the perturbative predictions for inclusive W-plus-dijet processes at the Large Hadron Collider. This instability can be cured by summing the leading-logarithmic contributions in $$ \hat{s}/{p}_t^2 $$ to all orders in αs. As expected though, leading logarithmic accuracy is insufficient to guarantee a suitable description in regions of phase space away from the high energy limit.We present (i) the first calculation of all partonic channels contributing at next-to-leading logarithmic order in W-boson production in association with at least two jets, and (ii) bin-by-bin matching to next-to-leading fixed-order accuracy. This new perturbative input is implemented in High Energy Jets, and systematically improves the description of available experimental data in regions of phase space which are formally subleading with respect to $$ \hat{s}/{p}_t^2 $$ .- 12 April 2021
