Vector Boson Scattering Processes: Status and Prospects / Buarque Franzosi, Diogo (Chalmers U. Tech. ; Goteborg, ITP) ; Gallinaro, Michele (LIP, Lisbon) ; Ruiz, Richard (Cracow, INP) ; Aarrestad, Thea K. (CERN) ; Cetorelli, Flavia (Milan U. ; INFN, Milan Bicocca) ; Chiesa, Mauro (Pavia U.) ; Costantini, Antonio (Louvain U., CP3) ; Denner, Ansgar (Wurzburg U.) ; Dittmaier, Stefan (Freiburg U.) ; Franken, Robert (Wurzburg U.) et al.
Insight into the electroweak (EW) and Higgs sectors can be achieved through measurements of vector boson scattering (VBS) processes. The scattering of EW bosons are rare processes that are precisely predicted in the Standard Model (SM) and are closely related to the Higgs mechanism. [...]

Precise predictions for same-sign W-boson scattering at the LHC / Ballestrero, Alessandro (INFN, Turin) ; Biedermann, Benedikt (Wurzburg U.) ; Brass, Simon (Siegen U.) ; Denner, Ansgar (Wurzburg U.) ; Dittmaier, Stefan (Freiburg U.) ; Frederix, Rikkert (Munich, Tech. U.) ; Govoni, Pietro (INFN, Milan Bicocca ; Milan U.) ; Grossi, Michele (Pavia U. ; INFN, Pavia) ; Jäger, Barbara (Tubingen U.) ; Karlberg, Alexander (Zurich U.) et al.
Vector-boson scattering processes are of great importance for the current run-II and future runs of the Large Hadron Collider. The presence of triple and quartic gauge couplings in the process gives access to the gauge sector of the Standard Model (SM) and possible new-physics contributions there. [...]

Combined NLO EW and QCD corrections to off-shell $\text {t} \overline{\text {t}}\text {W} $ production at the LHC / Denner, Ansgar (Wurzburg U.) ; Pelliccioli, Giovanni (Wurzburg U.)
The high luminosity that will be accumulated at the LHC will enable precise differential measurements of the hadronic production of a top--antitop-quark pair in association with a $\text{W}$ boson. Therefore, an accurate description of this process is needed for realistic final states. [...]

Direct determination of $\sin^2 \theta^\ell_{eff}$ at hadron colliders / Chiesa, Mauro (Wurzburg U.) ; Piccinini, Fulvio (INFN, Pavia) ; Vicini, Alessandro (CERN ; Milan U. ; INFN, Milan)
We discuss the renormalization of the electroweak Standard Model at 1-loop using the leptonic effective weak mixing angle as one of the input parameters. We evaluate the impact of this choice in the prediction of the forward-backward asymmetry for the neutral current Drell-Yan process. [...]

Different polarization definitions in same-sign $WW$ scattering at the LHC / Ballestrero, Alessandro (INFN, Turin) ; Maina, Ezio (INFN, Turin ; Turin U.) ; Pelliccioli, Giovanni (Wurzburg U.)
We study the polarization of positively charged $W$'s in the scattering of massive electroweak bosons at hadron colliders. We rely on the separation of weak boson polarizations in the gauge-invariant, doubly-resonant part of the amplitude in Monte Carlo simulations. [...]

Analytic integration of soft and collinear radiation in factorised QCD cross sections at NNLO / Magnea, Lorenzo (CERN ; Turin U. ; INFN, Turin) ; Pelliccioli, Giovanni (Wurzburg U.) ; Signorile-Signorile, Chiara (Turin U. ; INFN, Turin ; KIT, Karlsruhe, Dept. Phys.) ; Torrielli, Paolo (Turin U. ; INFN, Turin) ; Uccirati, Sandro (Turin U. ; INFN, Turin)
Within the framework of local analytic sector subtraction, we present the full analytic integration of double-real and real-virtual local infrared counterterms that enter NNLO QCD computations with any number of massless final-state partons. We show that a careful choice of phase-space mappings leads to simple analytic results, including non-singular terms, that can be obtained with conventional integration techniques..

Split NMSSM from dimensional reduction of a $10D$, $\mathcal{N}=1$$E_8$ over $SU(3)/U(1)\times U(1)\times Z_3$ / Patellis, Gregory (Lisbon, CFTP) ; Porod, Werner (Wurzburg U.) ; Zoupanos, George (Natl. Tech. U., Athens ; Munich, Max Planck Inst. ; CERN)
We examine an extension of the Standard Model which results from a $10D$, $\mathcal{N}=1$, $E_8$ gauge theory. The theory is dimensionally reduced over a $M_4 \times B_0/ \mathbf{Z}_3 $ space, where $B_0$ is the nearly-Kähler manifold $SU(3)/U(1) \times U(1)$ and $\mathbf{Z}_3$ is a freely acting discrete group on $B_0$ that triggers a Wilson flux breaking, leading to an $\mathcal{N}=1$, $SU(3)^3\times U(1)^2$ effective theory in $4D$.

Characterization of the ATLAS Micromegas quadruplet prototype / Sidiropoulou, O (CERN ; Wurzburg U.) ; Bianco, M (CERN) ; Danielsson, H (CERN) ; Degrange, J (CERN) ; Farina, E M (CERN ; INFN, Pavia ; Pavia U.) ; Gomez, F P (CERN) ; Iengo, P (CERN) ; Kuger, F (CERN ; Wurzburg U.) ; Lin, T H (Mainz U., Inst. Phys.) ; Schott, M (Mainz U., Inst. Phys.) et al.
A Micromegas [1] detector with four active layers, serving as prototype for the upgrade of the ATLAS muon spectrometer [2] , was designed and constructed in 2014 at CERN and represents the first example of a Micromegas quadruplet ever built. The detector has been realized using the resistive-strip technology and decoupling the amplification mesh from the readout structure. [...]

Polarized Z bosons from the decay of a Higgs boson produced in association with two jets at the LHC / Maina, Ezio (INFN, Turin ; Turin U.) ; Pelliccioli, Giovanni (U. Wurzburg (main))
Investigating the polarization of weak bosons provides an important probe of the scalar and gauge sector of the Standard Model. This can be done in the Higgs decay to four leptons, whose Standard-Model leading-order amplitude enables to generate polarized observables from unpolarized ones via a fully-differential reweighting method.
