Four-top quark physics at the LHC [PDF]
Universe, 2022 The production of four top quarks presents a rare process in the Standard Model that provides unique opportunities and sensitivity to Standard Model observables including potential enhancement of many popular new physics extensions.

Four-top as probe of light top-philic New Physics [PDF]
Journal of High Energy Physics, 2019 We study the four-top (t t ¯ $$ \overline{t} $$ t t ¯ $$ \overline{t} $$ ) final state at the LHC as a probe for New Physics (NP) effects due to new particles that couple predominantly to the top quark and whose masses are below the top-quark-pair ...

Top-quark physics at the CLIC electron-positron linear collider [PDF]
Journal of High Energy Physics, 2019 The Compact Linear Collider (CLIC) is a proposed future high-luminosity linear electron-positron collider operating at three energy stages, with nominal centre-of-mass energies s $$ \sqrt{s} $$ = 380 GeV, 1.5 TeV, and 3 TeV.

International Journal of Modern Physics A, 2015 We review the present situation in top quark physics, in these early days of Run II of the LHC. We take mostly a Standard Model perspective, showing recent results, and review the key concepts and results of the associated theoretical predictions. The issues we discuss are the top quark mass, top quark pair and single top production, production in ...

UV physics from IR features: New prospects from top flavor violation [PDF]
Physical Review D, 2023 New physics in the rare top decays $t \to q \ell^+\ell^-$ is currently very weakly constrained. We show that in a large class of Standard Model extensions, existing experimental constraints on new physics in flavor-conserving processes imply strong ...

Anomalies in bottom from new physics in top [PDF]
Physics Letters B, 2018 We analyze the possibility to accommodate current b→sℓ+ℓ− anomalies with TeV-scale mediators that couple to right-handed top quarks and muons, contributing to b→sℓ+ℓ− at the one-loop level.

Top-quark physics: Status and prospects [PDF]
Progress in Particle and Nuclear Physics, 2017 After the discovery of the top quark more than 20 years ago, its properties have been studied in great detail both in production and in decay. Increasingly sophisticated experimental results from the Fermilab Tevatron and from Run 1 and Run 2 of the LHC ...

International Journal of Modern Physics A, 2008 A review is presented of the current experimental status of the top quark sector of the Standard Model. The measurements summarized include searches for electroweak single top production, the latest results on the [Formula: see text] production cross-section, and searches for new physics in top quark production and decay.

Quantum detection of new physics in top-quark pair production at the LHC [PDF]
Journal of High Energy PhysicsThe recent observation of entanglement between top and anti-top quarks at the LHC opens the way to interpreting collider data with quantum information tools. In this work we investigate the relevance of quantum observables in searches of new physics.
