A bstract The search for effective field theory deformations of the Standard Model (SM) is a
major goal of particle physics that can benefit from a global approach in the framework of the …

A measurement of the associated production of a top-quark pair (tt¯) with a vector boson (W,
Z) in proton-proton collisions at a center-of-mass energy of 13 TeV is presented, using 36.1 …

A search for the associated production of the Higgs boson with a top quark pair (tt¯ H) is
reported. The search is performed in multilepton final states using a data set corresponding …

A bstract We present a novel framework for carrying out global analyses of the Standard
Model Effective Field Theory (SMEFT) at dimension-six: SMEFiT. This approach is based on …

A bstract Measurements are presented of the differential cross sections for Z bosons
produced in proton-proton collisions at\(\sqrt {s}\)= 13 TeV and decaying to muons and …

Four-lepton production in proton-proton collisions, $\mathrm {pp}\to (\mathrm
{Z}/\gamma^*)(\mathrm {Z}/\gamma^*)\to 4\ell $, where $\ell=\mathrm {e} $ or $\mu $, is …

A bstract 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 …

A bstract A search for direct production of top squark pairs in events with jets and large
transverse momentum imbalance is presented. The data are based on proton-proton …

Inclusive and differential cross-sections for the production of a top-quark pair in association
with a photon are measured with proton-proton collision data corresponding to an integrated …

A bstract The production cross section of a top quark pair in association with a photon is
measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The data set …
