/ Abdolmaleki, Hamed (IPM, Tehran ; Lorestan U.) ; Amoroso, Simone (DESY) ; Britzger, Daniel (Munich, Max Planck Inst.) ; Dattola, Filippo (DESY) ; Fiaschi, Juri (INFN, Milan Bicocca ; Milan Bicocca U.) ; Giuli, Francesco (CERN) ; Glazov, Alexander (DESY) ; Hautmann, Francesco (CERN ; Antwerp U. ; Oxford U.) ; Luszczak, Agnieszka (Cracow Tech. U.) ; Taheri Monfared, Sara (DESY) et al.
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 xFitter, we investigate the impact of high-statistics measurements of the neutral current DY (NCDY) forward-backward asymmetry $A_{\rm{FB}}$ near the weak boson mass scale in the present and forthcoming stages of the Large Hadron Collider (LHC).

An overwhelming number of theoretical predictions for hadron colliders require parton distribution functions (PDFs), which are an important ingredient of theory infrastructure for the next generation of high-energy experiments. This whitepaper summarizes the status and future prospects for determination of high-precision PDFs applicable in a wide range of energies and experiments, in particular in precision tests of the Standard Model and in new physics searches at the high-luminosity Large Hadron Collider and Electron-Ion Collider [...]

The Forward Physics Facility at the High-Luminosity LHC
/ Feng, Jonathan L. (UC, Irvine) ; Kling, Felix (DESY) ; Reno, Mary Hall (Iowa U.) ; Rojo, Juan (NIKHEF, Amsterdam ; Vrije U., Amsterdam) ; Soldin, Dennis (Delaware U.) ; Anchordoqui, Luis A. (Lehman Coll.) ; Boyd, Jamie (CERN) ; Ismail, Ahmed (Oklahoma State U.) ; Harland-Lang, Lucian (Oxford U. ; Oxford U., Theor. Phys.) ; Kelly, Kevin J. (CERN) et al.
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located several hundred meters from the ATLAS interaction point and shielded by concrete and rock, will host a suite of experiments to probe Standard Model (SM) processes and search for physics beyond the Standard Model (BSM) [...]

/xfitter Developers’ Team
We present the first open-source analysis of fragmentation functions (FFs) of charged pions (entitled IPM-xFitter) computed at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) accuracy in perturbative QCD using the xFitter framework. This study incorporates a comprehensive and up-to-date set of pion production data from single-inclusive annihilation (SIA) processes, as well as the most recent measurements of inclusive cross-sections of single pion by the BELLE collaboration.

We investigate the impact of high-statistics Drell-Yan (DY) measurements at the LHC on the study of non-perturbative QCD effects from parton distribution functions (PDF). We present the results of a PDF profiling analysis based on the neutral-current DY forward-backward asymmetry, using the open source fit platform xFitter..

The Large Hadron-Electron Collider at the HL-LHC
/ FCC-he Study Group Collaboration
The Large Hadron electron Collider, LHeC, is the means to move deep inelastic physics following HERA to the energy frontier of particle physics as it is being exploited by the HL-LHC. The paper presents a thorough update of the initial LHeC Conceptual Design Report (CDR) published in 2012. [...]
