QCD & EW III
- Tobias Neumann (Fermi National Accelerator Laboratory)
WH, ZH, W+W−, and W±Z pair production probes the significance of non-Standard Model interactions of quarks, gauge bosons, and the Higgs boson. These new effects can be quantified in terms of effective field theory (EFT) coefficients. We examine the importance of including next-to-leading order QCD corrections in fits to the EFT coefficients. We explore different approaches to enforcing the...
We study the potential of future Electron-Ion Collider (EIC) data to probe four-fermion operators in the Standard Model Effective Field Theory (SMEFT). The ability to perform measurements with both polarized electron and proton beams at the EIC provides a powerful tool that can disentangle the effects from different SMEFT operators. We compare the potential constraints from an EIC with those...
In this talk I will present results obtained using the previously developed projective phase space generator for the calculation of the vector boson plus one jet at next-to-leading order in QCD. I will comment on the scalability of the projective phase space generator and further directions of the research.
The production of multiple weak vector bosons at the LHC constitutes a stringent test of the electroweak sector and provide a model-independent means to search for new physics at the TeV scale. In this talk, we present the latest results from the ATLAS experiment for multi-boson production in proton-proton collisions at √s=13 TeV. The measurements exploit both the leptonic and hadronic decays...
Precision measurements of the production cross-sections of W/Z boson at LHC provide important tests of perturbative QCD and information about the parton distribution functions for quarks within the proton. In this talk, we present a variety of measurements that probe the production of weak bosons in proton-proton collisions at a variety of collision energies. For inclusive production of W and...
The production of jets and prompt isolated photons at hadron colliders provides stringent tests of perturbative QCD and can be used to evaluate the probability density functions of partons in the proton. In this talk we discuss a variety of measurements in this section done using proton-proton collision data collected by the ATLAS experiment at √s=13 TeV . For final states containing photons,...
Progress in our ability to compute scattering cross sections has allowed us to obtain prediction for key collider processes at Next-to-next-to-next-to leading order (N3LO) in QCD perturbation theory. I discuss the implications of this progress on our understanding of the Drell-Yan cross section, on differential predictions for Higgs boson observables and on the precision phenomenology program...
