Probing the CP structure of the top quark Yukawa at the future muon collider

open access: yesJournal of High Energy Physics
We study the top-Higgs coupling with a CP violating phase ξ at a future multi-TeV muon collider. We focus on processes that are directly sensitive to the top quark Yukawa coupling: t t ¯ h $$ t\overline{t}h $$ , tbhμν, and t t ¯ hν ν ¯ $$ t\overline{t} h\

On the impact of the mixed Z/γ PDF at muon colliders

open access: yesJournal of High Energy Physics
We study the role of the Z/γ-interference parton distribution function (PDF) in high-energy muon colliders. We review how this PDF emerges when electroweak interactions are applied to the collinear splitting process and show that the leading-order ...

Higgs anomalous couplings, FCNC and LFV decays

open access: yes, 2019
An overview of searches for the lepton flavor violating decays of the Higgs boson, and for flavor changing neutral currents in Hqt couplings are presented from the ATLAS. In addition, different approaches on the Higgs anomalous couplings to vector bosons from the two experiments are presented.

Exploring Higgs EFT in t t ¯ hh $$ t\overline{t} hh $$ at high luminosity LHC

open access: yesJournal of High Energy Physics
The non-resonant production of a Higgs boson pair in association with a top-antitop quark pair pp → t t ¯ hh $$ \left( pp\to t\overline{t} hh\right) $$ has only recently begun to be explored at the Large Hadron Collider (LHC) and provides a unique and ...

e + e − → ZH process in the SMEFT beyond leading order

open access: yesJournal of High Energy Physics
We systematically study potential effects of Beyond the Standard Model physics in the e + e − → ZH process. To this end, we include all relevant dimension-6 Standard Model Effective Field Theory operators and work to next-to-leading order (NLO) accuracy ...

Lepton flavor violation in Higgs boson decays at the HL-LHC

open access: yesJournal of High Energy Physics
We explore the discovery potential for lepton flavor-violating Higgs boson decays, h → ℓ i ℓ j (ℓ i ≠ ℓ j ; ℓ = e, μ, τ), in proton-proton collisions.

Exotic h → Za Higgs decays into τ leptons

open access: yesJournal of High Energy Physics
Exotic Higgs decays are among the most promising areas to be explored at the High-Luminosity LHC, given the unprecedentedly large amount (~ 3 × 108) of 125 GeV Higgs bosons that will be produced. In this context, we propose a new search channel for which
