Exploring SMEFT couplings using the forward–backward asymmetry in neutral current Drell–Yan production at the LHC / 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).

LHC sensitivity to Z'/W' states in composite Higgs models / Fiaschi, J. (Liverpool U.) ; Giuli, F. (CERN ; Rome U., Tor Vergata ; INFN, Rome2 ; Brandeis U.) ; Hautmann, F. (CERN ; Antwerp U. ; Oxford U.) ; Moretti, S. (Southampton U. ; Uppsala U.)
Using the 4-Dimensional Composite Higgs Model (4DCHM) realization of the minimal composite Higgs scenario, we discuss the Large Hadron Collider (LHC) sensitivity to new physics signals from multiple $Z^\prime$ and $W^\prime$ broad resonances. We illustrate the role of systematic uncertainties due to QCD effects encoded in parton distribution functions for experimental searches in leptonic channels. [...]

$\mathbf{Z^\prime}$-boson dilepton searches and the high-$\mathbf{x}$ quark density / Fiaschi, J. (Liverpool U., Dept. Math.) ; Giuli, F. (CERN) ; Hautmann, F. (CERN ; Antwerp U. ; Oxford U.) ; Moch, S. (Hamburg U., Inst. Theor. Phys. II) ; Moretti, S. (Southampton U. ; Uppsala U.)
We study the influence of theoretical systematic uncertainties due to the quark density on LHC experimental searches for $Z^\prime$-bosons. Using an approach originally proposed in the context of the ABMP16 PDF set for the high-$x$ behaviour of the quark density, we presents results on observables commonly used to study $Z^\prime$ signals in dilepton channels..

Enhancing the Large Hadron Collider Sensitivity to Charged and Neutral Broad Resonances of New Gauge Sectors / Fiaschi, Juri (Liverpool U., Dept. Math.) ; Giuli, Francesco (CERN ; INFN, Rome2 ; Rome U., Tor Vergata) ; Hautmann, Francesco (Antwerp U. ; Oxford U.) ; Moretti, Stefano (Southampton U.)
In scenarios beyond the Standard Model (BSM) characterized by charged ($W^\prime$) or neutral ($Z^\prime$) massive gauge bosons with large width, resonant mass searches are not very effective, so that one has to exploit the tails of the mass distributions measured at the Large Hadron Collider (LHC). In this case, the LHC sensitivity to new physics signals is influenced significantly by systematic uncertainties associated with the Parton Distribution Functions (PDF), particularly in the valence quark sector relevant for the multi-TeV mass region.

Complementarity of Lepton-Charge and Forward-Backward Drell-Yan Asymmetries for Precision Electroweak Measurements and Quark Density Determinations / Fiaschi, Juri (Liverpool U., Dept. Math.) ; Giuli, Francesco (CERN ; INFN, Rome2 ; Rome U., Tor Vergata) ; Hautmann, Francesco (Antwerp U. ; Oxford U.) ; Moretti, Stefano (Southampton U.)
We address the impact of future measurements of charged and neutral current Drell-Yan (DY) asymmetries and their combination on Parton Distribution Functions (PDFs) uncertainties. We quantify the reduction of PDF uncertainties using the QCD tool xFitter. [...]

Math.) ; Giuli, Francesco (CERN ; INFN, Rome2 ; Rome U., Tor Vergata) ; Hautmann, Francesco (Antwerp U. ; Oxford U.) ; Moretti, Stefano (Southampton U.)
Precision determinations of Standard Model (SM) Electro-Weak (EW) parameters at the Large Hadron Collider (LHC) are dominated by uncertainties due to Parton Distribution Functions (PDFs). Reweighting and profiling techniques are routinely employed to treat this. [...]

Singlet-doublet/triplet dark matter and neutrino masses / Fiaschi, Juri (Munster U., ITP) ; Klasen, Michael (Munster U., ITP) ; May, Simon (Garching, Max Planck Inst. ; Munster U., ITP)
In these proceedings, we present a study of a combined singlet--doublet fermion and triplet scalar model for dark matter (DM). Together, these models form a simple extension of the Standard Model (SM) that can account for DM and explain the existence of neutrino masses, which are generated radiatively. [...]

Longitudinal Z-Boson Polarization and the Higgs Boson Production Cross Section at the Large Hadron Collider / Amoroso, S. (DESY) ; Fiaschi, J. (Liverpool U., Dept. Math. ; Munster U., ITP) ; Giuli, F. (CERN ; Rome U., Tor Vergata ; INFN, Rome) ; Glazov, A. (DESY) ; Hautmann, F. (Antwerp U. ; Oxford U., Theor. Phys.) ; Zenaiev, O. (CERN)
Charged lepton pairs are produced copiously in high-energy hadron collisions via electroweak gauge boson exchange, and are one of the most precisely measured final states in proton-proton collisions at the Large Hadron Collider (LHC). We propose that measurements of lepton angular distributions can be used to improve the accuracy of theoretical predictions for Higgs boson production cross sections at the LHC. [...]
