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…

Searches for Extra Higgs Bosons using Higgs{} Events within 2HDMs: Direct versus Indirect Probes
Esteban Chalbaud, Stefania De Curtis, Luigi Delle Rose +3
We study the possibility of establishing the production of additional Higgs states in the process , where = , with being CP-even and $…

Asymmetries in invisible Dark Matter mediator production associated with final states
E. Chalbaud, Rui M. Silva, António Onofre +2
In this paper, we propose two sets of different CP-sensitive observables inspired by the Higgs production in association with the top quark. We employ a Dark Matter simplified mode…
