Direct measurements of processes involving QCD jets provide a key probe of QCD interactions, and in which, the multi-jet and vector boson plus jets processes are key channels in this measurement program. This talk presents recent measurements in this sector from the ATLAS experiment.

The predictions relevant for two recent measurements by ATLAS have highlighted the necessity of developing methods to systematically tackle the intricate behaviour of large logarithmic corrections in the perturbative series in order for predictions to be accurate and useful. Specifically, the analysis of the processes of the production of at least two jets ($pp\to jj$...

The precision measurements of Drell-Yan processes offer in-depth understanding of QCD interactions and important constraints on SM parameters and PDFs. This talk presents recent Drell-Yan precision results from the ATLAS experiment.

The production of two isolated photons in high-energy hadron collisions poses a challenge to perturbative QCD because of large corrections through next-to-next-to-leading order (NNLO). We present novel next-to-next-to-next-to-leading order (N3LO) predictions and finally demonstrate perturbative convergence for this process. We discuss the considerable computational challenges and...

Lepton colliders produce large fluxes of quasi-real photons via the equivalent photon approximation. We present a study for the proposed FCC-ee, showing these fluxes enable a broad photon-QCD program.

While photon-induced dijet production gives access, for example, to $\alpha_S$ determinations, jet substructure, etc., the talk centers on deep-inelastic scattering of leptons on collinear... -

With exciting future collider programs, such as the FCCee, on the horizon, interpretation of precision measurements at these facilities requires us to have already constrained the Standard Model parameters to a high degree of precision. Collider measurements impacted by strong interactions such as the strong coupling constant and the top quark mass remain bottlenecks in this program. In this...

We study the impact of fiducial acceptance cuts on Energy-Energy Correlators (EECs) in $e^+e^-$ annihilation into hadrons. Experimental measurements of EECs typically impose an angular acceptance defined with respect to oriented event-shape axes, such as thrust or sphericity, and correct the resulting phase-space loss using Monte Carlo efficiency factors.

Recent advances in data preservation and modern analysis techniques have enabled a new generation of precision measurements using archived electron-positron collision data collected at the Large Electron-Positron Collider (LEP). The Electron-Positron Alliance is developing a broad physics program that applies contemporary experimental and theoretical tools to these unique datasets,...

It has recently been proposed that collider events can be equipped with a metric, the Energy Mover's Distance (EMD), which allows one to rephrase multiple aspects of collider physics in a geometric language. Further, the EMD can be exploited to define new observables. In this context, event isotropy quantifies the resemblance of an event to a uniform energy distribution. We present the first...

The inclusive cross sections for charm ($c\bar c$) and bottom ($b\bar b$) quark-antiquark pair production in proton-proton, proton-antiproton, and proton-nucleus collisions are studied over a wide range of center-of-mass energies, $\sqrt{s} = 10$ GeV--400 TeV. All existing data over $\sqrt{s} = 10$ GeV--14 TeV are collected and compared to calculations at next-to-next-to-leading-order (NNLO)...

We report the first observation of the production of high-transverse-momentum jets and electroweak bosons in association with a tagged forward proton in proton–proton collisions at a center-of-mass energy of 13.6 TeV. The analysis uses 2.0 fb(^{-1}) of data collected by the CMS experiment during dedicated low-pileup LHC operation in 2026. Forward protons carrying 85–97% of the beam energy are...

I will discuss a new class of non-global observables defined by a veto on transverse-energy ($E_T$) flow inside an azimuthal interval $\Delta\phi$ about a chosen reference axis. Such vetoes are widely used in LHC measurements involving missing transverse momentum, yet they probe a kinematic regime whose logarithmic structure has not been explored before. We show that these observables exhibit...

The electron-positron stage of the Future Circular Collider (FCC-ee) is aiming at direct and indirect searches for physics beyond the SM in a new 91-km tunnel at CERN. In addition, the FCC-ee offers unique possibilities for high-precision studies of the strong interaction in the clean environment provided by ee collisions, thanks to its broad span of center-of-mass energies, ranging from the Z...

The immense flux of high-momentum jets produced by the LHC provides a unique opportunity to study the detailed dynamics of high-energy QCD. So-called “energy-energy correlator” observables provide a particularly compelling opportunity to uncover these dynamics by probing the internal structure of jets while maintaining a close connection to fundamental ingredients of QCD theory. The bulk...
