New physics in toponium's shadow?
Thomas Flacke, Benjamin Fuks, Dongchan Kim +3
ATLAS and CMS have recently reported enhancements in the top-antitop production rate near threshold, a region where non-perturbative QCD dynamics associated with toponium formation…
Extracting a Toponium Signal at the LHC with Spin and Quantum Information Tools
Laura Antozzi, Esteban Chalbaud, Frédéric Déliot +6
We investigate near-threshold top-antitop production at the LHC, focusing on the impact of toponium formation on spin correlations and quantum information properties of the final s…
Prospects for toponium formation at the LHC in the single-lepton mode
Benjamin Fuks, Kaoru Hagiwara, Kai Ma +2
We investigate the formation of toponium in the single-leptonic final state at the LHC. Our study builds on our recently proposed framework that incorporates the associated non-per…
Deep learning approaches to top FCNC couplings to photons at the LHC
Benjamin Fuks, Sumit K. Garg, A. Hammad +1
We investigate the sensitivity of the LHC to flavour-changing neutral current interactions involving the top quark and a photon using a model-independent effective field theory fra…
Long-lived Left-Right signals at the FCC-ee
Benjamin Fuks, Jonathan Kriewald, Miha Nemevšek +1
We give an extensive discussion of the displaced signals of heavy Majorana neutrino production at future electron-positron colliders operating at various proposed energies in the c…
Statistical Indications of Toponium Formation in Top Quark Pair Production
Benjamin Fuks, Aminul Hossain, James Keaveney
We present an analysis of six differential cross-section measurements of top-quark pair production in the dilepton channel from the ATLAS and CMS experiments. The data are compared…
