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. [...]

Dark Matter Signals at the LHC from a 3HDM / Rojas-Ciofalo, Diana (Southampton U.) ; Cordero, Adriana (Puebla U., Inst. Fis.) ; Hernández-Sánchez, Jaime (Puebla U., Inst. Fis.) ; Keus, Venus (Helsinki Inst. of Phys. ; Helsinki U.) ; Moretti, Stefano (Southampton U.) ; Sokolowska, Dorota (IIP, Brazil)
We analyse new signals of Dark Matter (DM) at the Large Hadron Collider (LHC) in a 3-Higgs Doublet Model (3HDM) where only one doublet acquires a Vacuum Expectation Value (VEV), preserving a parity $Z_2$. The other two doublets are inert and do not develop a VEV, leading to a dark scalar sector controlled by $Z_2$, with the lightest CP-even dark scalar $H_1$ being the DM candidate. [...]

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. [...]

${}^8$Be Decay Anomaly and Light $Z'$ / Delle Rose, Luigi (Southampton U. ; INFN, Florence ; Florence U.) ; Khalil, Shaaban (Zewail City Sci. Technol., Giza) ; King, Simon J.D. (Southampton U. ; INFN, Padua ; Padua U.) ; Moretti, Stefano (Southampton U. ; Rutherford) ; Thabt, Ahmed M. (Zewail City Sci. Technol., Giza)
In this proceedings, we discuss a light (17 MeV) $Z'$ solution to the anomaly observed in the decay of Beryllium-8 by the Atomki collaboration. We detail an anomaly free model with minimal particle content which can satisfy all other experimental constraints with gauge couplings $\mathcal{O}(10^{-4})$..
