Focus topics for the ECFA study on Higgs / Top / EW factories

In order to stimulate new engagement and trigger some concrete studies in areas where further work would be beneficial towards fully understanding the physics potential of an $e^+e^-$ Higgs / Top / Electroweak factory, we propose to define a set of focus topics. [...]

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

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. [...]

Production of $t \bar{t} b \bar{b}$ at the LHC at NLO QCD
/ Bredenstein, Axel (KEK, Tsukuba) ; Denner, Ansgar (PSI, Villigen) ; Dittmaier, Stefan (Freiburg U.) ; Pozzorini, Stefano (CERN)
We summarise predictions for top anti-top bottom anti-bottom (tTbB) production at the LHC in next-to-leading order QCD. The precise description of this background process is a prerequisite to observe associated top anti-top Higgs production in the H -> bottom anti-bottom decay channel. [...]

NLO QCD corrections to top anti-top bottom anti-bottom production at the LHC
/ Bredenstein, Axel (KEK, Tsukuba) ; Denner, Ansgar (PSI, Villigen) ; Dittmaier, Stefan (Freiburg U.) ; Pozzorini, Stefano (CERN)
The next-to-leading order (NLO) QCD corrections to top anti-top bottom anti-bottom (tTbB) production at the LHC reveal that the scale choice adopted in previous lowest-order simulations underestimates the tTbB cross section by a factor two. We discuss a new dynamical scale that stabilizes the perturbative predictions and describe the impact of the corrections on the shape of distributions. [...]
