Limitations of quantum tomography in Higgs-boson decays to four leptons
Morgan Del Gratta, Fabio Maltoni, Davide Pagani +1
We investigate the limitations of the two-qutrit quantum tomography in Higgs-boson decays to four charged leptons. At next-to-leading order, the standard reconstruction can yield a…
Simulations and flavour-scheme studies for Higgs-boson production in association with charm quarks
Tiziano Bevilacqua, Christian Biello, Lea Michela Caminada +5
We present a detailed NLO+PS study of Higgs-boson production in association with charm and bottom quarks, with particular focus on the modelling of the H+c final state. We systemat…
Constraining the Higgs potential using multi-Higgs production
Jia-Le Ding, Zach Gillis, Ulrich Haisch +10
The Higgs self-couplings remain only weakly constrained by current Large Hadron Collider (LHC) measurements, leaving ample room for physics beyond the Standard Model that could mod…
Z-boson quantum tomography at next-to-leading order
Morgan Del Gratta, Federica Fabbri, Michele Grossi +4
We investigate the origin of the unusually large electroweak (EW) radiative effects observed in the extraction of the spin-density matrix and related observables at colliders, focu…
Double neutral-current corrections to NLO electroweak leptonic cross sections
Stefano Frixione, Fabio Maltoni, Davide Pagani +1
We present a method for improving next-to-leading order electroweak (EW) predictions for lepton-scattering processes by consistently including double neutral-current corrections ar…
Precision phenomenology at multi-TeV muon colliders
Stefano Frixione, Fabio Maltoni, Davide Pagani +1
Future lepton colliders, such as those based on linear or circular accelerators, are expected to attain centre-of-mass energies in the multi-TeV range. In this re…
Quantum properties of : precise predictions in the SM and sensitivity to new physics
Morgan Del Gratta, Federica Fabbri, Priyanka Lamba +2
We study the quantum properties of the Higgs-boson decays into four fermions via two vector bosons . In particular, we focus on the case of two different-flavour…
Quantum Information meets High-Energy Physics: Input to the update of the European Strategy for Particle Physics
Yoav Afik, Federica Fabbri, Matthew Low +68
Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy la…
Electroweak corrections in the SMEFT: four-fermion operators at high energies
Hesham El Faham, Ken Mimasu, Davide Pagani +3
In the Standard Model (SM), electroweak (EW) corrections become significant at high energies, particularly at the tera-electronvolt scale and beyond, due to the presence of Sudakov…
Higgs-muon interactions at a multi-TeV muon collider
Yang Ma, Eugenia Celada, Tao Han +7
We establish a simple yet general parameterization of Higgs-muon interactions within the effective field theory frameworks, including both the Higgs Effective Field Theory (HEFT) a…
EW corrections and Heavy Boson Radiation at a high-energy muon collider
Yang Ma, Davide Pagani, Marco Zaro
In this work we investigate several phenomenological and technical aspects related to electroweak (EW) corrections at a high-energy muon collider, focusing on direct production pro…
Top-quark pair production as a probe of light top-philic scalars and anomalous Higgs interactions
Fabio Maltoni, Davide Pagani, Simone Tentori
We compute the effects due to the virtual exchange (or the soft emission) of a scalar particle with generic couplings to the top quark in pair production at the LHC. We a…
Probing Higgs-muon interactions at a multi-TeV muon collider
Eugenia Celada, Tao Han, Wolfgang Kilian +7
We study the capabilities of a muon collider, at 3 and 10 TeV center-of-mass energy, of probing the interactions of the Higgs boson with the muon. We consider all the possible proc…
Top-philic ALP phenomenology at the LHC: the elusive mass-window
Simone Blasi, Fabio Maltoni, Alberto Mariotti +3
We study the LHC phenomenology of an Axion Like Particle (ALP) that couples only derivatively with the top quark at tree level. We inspect the radiatively induced couplings with th…
