W-boson helicity fractions in top decay as probes of dimension-6 and dimension-8 SMEFT operators
Afsaneh Kianfar, Gholamhossein Haghighat, Mojtaba Mohammadi Najafabadi
Precision measurements of top-quark decays provide powerful probes of physics beyond the Standard Model (SM). While the impact of dimension-6 operators in the SM Effective Field Th…
Exploring non-standard interactions at future electron-proton colliders
Gholamhossein Haghighat, Reza Jafari, Hamzeh Khanpour +1
In this paper, we use the charged-current Higgs boson production process at future electron-proton colliders, , with the subsequent decay of the Higgs boson into…
Probing a light dark sector at future lepton colliders via invisible decays of the SM-like and dark Higgs bosons
Gholamhossein Haghighat, Mojtaba Mohammadi Najafabadi, Kodai Sakurai +1
A renormalizable UV model for Axion-Like Particles (ALPs) or hidden photons, that may explain the dark matter usually involves a dark Higgs field which is a singlet under the stand…
Search for lepton-flavor-violating decays of the tau lepton at a future muon collider
Gholamhossein Haghighat, Mojtaba Mohammadi Najafabadi
Tau leptons can have lepton-flavor-violating (LFV) couplings to a muon or an electron and an Axion-Like Particle (ALP). ALPs are pseudo Nambu-Goldstone bosons associated with spont…
Search for lepton-flavor-violating ALPs at a future muon collider and utilization of polarization-induced effects
Gholamhossein Haghighat, Mojtaba Mohammadi Najafabadi
Axion-Like Particles (ALPs) are pseudo Nambu-Goldstone bosons associated with spontaneously broken global symmetries. Such particles can have lepton-flavor-violating (LFV) c…
