Updated predictions for toponium production at the LHC
M. V. Garzelli, G. Limatola, S. -O. Moch +2
We provide an update on QCD predictions for top-quark pair production close to threshold including bound state effects at the Large Hadron Collider. We compute the top-quark pair i…
NNLO PDFs driven by top-quark data
S. Alekhin, M. V. Garzelli, S. -O. Moch +1
We study the impact of state-of-the-art top-quark data collected at the Large Hadron Collider on parton distribution functions (PDFs). Following the ABMP methodology, the fit extra…
Exploring SMEFT Couplings Using the Forward-Backward Asymmetry in Neutral Current Drell-Yan Production at the LHC
Andrii Anataichuk, Sven-Olaf Moch, Hamed Abdolmaleki +12
Neutral current Drell-Yan (DY) lepton-pair production is considered in the framework of the Standard Model Effective Field Theory (SMEFT). Using the open-source fit platform xFitte…
A framework for simultaneous fit of QCD and BSM parameters with xFitter
XiaoMin Shen, Simone Amoroso, Jun Gao +2
An extension of the xFitter open-source program for QCD analyses is presented, allowing for a polynomial parameterization of the dependence of physical observables on theoretical p…
The azimuthal correlation between the leading jet and the scattered lepton in deep inelastic scattering at HERA
ZEUS Collaboration, I. Abt, R. Aggarwal +78
The azimuthal correlation angle, , between the scattered lepton and the leading jet in deep inelastic scattering at HERA has been studied using data collected with…
xFitter Updates: Probing Z Boson Couplings with Forward-Backward Asymmetry
Oleksandr Zenaiev
We present recent updates in the xFitter software framework for global fits of parton distribution functions in high-energy physics. Our focus is on investigating the sensitivity t…
