3. Complete SMEFT predictions for four top quark production at hadron colliders

Hesham El Faham (The University of Manchester)

6/20/23, 4:55 PM

We study four top quark production at hadron colliders in the Standard Model Effective Field Theory (SMEFT). We perform an analysis at the tree-level, including all possible QCD- and EW-coupling orders and relevant dimension-six operators. We find several cases where formally subleading terms give rise to significant contributions, potentially providing sensitivity to a broad class of...

11. Top-quark couplings at current and future colliders

Victor Miralles (INFN sezione di Roma)

6/20/23, 5:25 PM

In this work the prospects for measurements of the top-quark couplings at future colliders are presented. Projections are presented for the high luminosity phase of the Large Hadron Collider and a future Higgs/electroweak/top factory lepton collider. Results are presented for the expected bounds on Wilson coefficients of the relevant SMEFT operators from a global fit to the top-quark sector.

16. The top quark legacy of the LHC Run II for PDF and SMEFT analyses

James Moore

6/20/23, 5:55 PM

We assess the impact of top quark production at the LHC on global analyses of parton distributions (PDFs) and of Wilson coefficients in the SMEFT, both separately and in the framework of a joint interpretation. We consider the broadest top quark dataset to date containing all available measurements based on the full Run II luminosity. First, we determine the constraints that this dataset...
