On two-body and three-body spin correlations in leptonic t(t)over-barZ production and anomalous couplings at the LHC

Rafiqul Rahaman

Summary: We study the anomalous t (t) over barZ couplings in the t (t) over barZ production at the 13 TeV LHC with leptonic final states. We utilize polarizations of top quarks and Z boson, two-body and three-body spin correlations, as well as the cross section to investigate the anomalous couplings. We provide parameter and simultaneous limits on the couplings of the effective vertex and effective operators for different luminosities.

Production and decay of the Higgs boson in association with top quarks

Daniel Stremmer et al.

Summary: This study reports on the calculation of next-to-leading order QCD corrections to Higgs boson production and decay associated with top quarks, considering hadronic processes resulting from top quark decays. Resonant and non-resonant Feynman diagrams, interferences, and off-shell effects are thoroughly investigated, along with the inclusion of Higgs boson decays in the narrow-width approximation. Different theoretical uncertainties and the impact of bottom-quark parton density contributions are also examined.

Multi-lepton probes of new physics and lepton-universality in top-quark interactions

Yoav Afik et al.

Summary: In this study, we explore the sensitivity to new physics (NP) in the associated production of top-quarks with leptons. The analysis focuses on the four-Fermi effective t((t) over bar)l(+)l(-) contact interactions generated by multi-TeV heavy scalar, vector, or tensor exchanges. The results show that the di-lepton and tri-lepton channels are better probes for the effective t((t) over bar)l(+)l(-) interactions, and the dominant backgrounds can be eliminated through proper selections and invariant mass criteria. The study provides new and tighter constraints on the scale of the ttll contact interactions.

NLO QCD corrections to full off-shell production of t(t)over-barZ including leptonic decays

Giuseppe Bevilacqua et al.

Summary: Motivated by ongoing searches for new physics in the top-quark sector at the Large Hadron Collider, this study calculates the NLO QCD corrections to the Standard Model process pp -> t (t) over barZ + X in the tetra-lepton decay channel. The calculation includes all resonant and non-resonant Feynman diagrams, interferences, and off-shell effects of the top quark, W and Z gauge bosons, as well as photon-induced contributions.

Hadronic production of top-quark pairs in association with a pair of leptons in the POWHEG BOX framework

Margherita Ghezzi et al.

Summary: In this study, we present an implementation of tt??t'+t'??? hadronic production in the POWHEG BOX framework, matched to parton-shower event generators at next-to-leading order in QCD. Our results show that off-shell effects in tt??t'+t'??? are generally small at the total cross section level, but can decrease the tail of the leptons' transverse momentum distributions by 10%-20%. These effects are visible beyond the scale uncertainty due to renormalization and factorization scale variation. Moreover, we find that accounting for top-quark decays with tree-level spin correlations also gives rise to 10%-20% effects in specific regions of the tt??t'+t'??? decayed final state.

Multi-lepton signatures of vector-like leptons with flavor: DO-TH 20/12

Stefan Bissmann et al.

Summary: We investigate collider signatures of standard model extensions involving vector-like leptons and a flavorful scalar sector. By focusing on Yukawa couplings and masses that can explain current data on muon and electron anomalous magnetic moments, we find that flavorful vector-like leptons may be excluded within certain mass ranges. We also design novel observables based on opposite sign opposite flavor invariant masses to signal new physics and extract mass hierarchies in upcoming searches at the LHC and the HL-LHC.

Topping-up multilepton plus b-jets anomalies at the LHC with a Z′ boson

Ezequiel Alvarez et al.

Summary: A phenomenological New Physics model involving a Z' boson coupling with up-type quarks is studied to explain discrepancies observed in experiments at the LHC. The model shows a better fit to experimental data compared to the Standard Model at a New Physics scale of around 500 GeV. A broadband search design is proposed to enhance LHC sensitivity to the signal from this model.
