Search for the t → ch decay at hadron colliders
Journal of High Energy Physics, 2019 We study the observability for the flavor-changing decay of a top quark t → ch at the Large Hadron Collider (LHC) and future hadron colliders, namely, High-Luminosity LHC (HL-LHC), High-Energy LHC (HE-LHC) and Future Circular hadron-hadron Collider (FCC ...

Two-body lepton-flavour-violating decays in a 2HDM with soft family-lepton-number breaking
Journal of High Energy Physics, 2022 We evaluate the decays ℓ 1 ± $$ {\ell}_1^{\pm } $$ → ℓ 2 ± γ $$ {\ell}_2^{\pm}\gamma $$ , Z → ℓ 1 + ℓ 2 − $$ {\ell}_1^{+}{\ell}_2^{-} $$ , and h → ℓ 1 + ℓ 2 − $$ {\ell}_1^{+}{\ell}_2^{-} $$ , where ℓ 1 and ℓ 2 are charged leptons with different flavours ...

Journal of High Energy Physics, 2019 Some interpretations of R D ∗ $$ {R}_{D^{\left(\ast \right)}} $$ anomaly in B meson decay using leptoquark (LQ) models can also generate top quark decays through Flavor Changing Neutral Current (FCNC). In this work we focus on two LQs, i.e.

Natural dark matter and light bosons with an alternative left-right symmetry
Journal of High Energy Physics, 2020 We perform a consistent analysis of the alternative left-right symmetric model emerging from E 6 grand unification. We include a large set of theoretical and experimental constraints, with a particular emphasis on dark matter observables and collider ...

Hadron collider probes of the quartic couplings of gluons to the photon and Z boson
Journal of High Energy Physics, 2022 We explore the experimental sensitivities of measuring the gg → Zγ process at the LHC to the dimension-8 quartic couplings of gluon pairs to the Z boson and photon, in addition to comparing them with the analogous sensitivities in the gg → γγ process ...

Probing Higgs couplings to light quarks via Higgs pair production
Journal of High Energy Physics, 2019 We consider the potential of the Higgs boson pair production process to probe the light quark Yukawa couplings. We show within an effective theory description that the prospects of constraining enhanced first generation light quark Yukawa couplings in ...

Charged lepton flavor violation and electric dipole moments in the inert Zee model
Journal of High Energy Physics, 2018 The inert Zee model is an extension of the Zee model for neutrino masses to allow for a solution to the dark matter problem that involves two vector-like fields, a doublet and a singlet of SU(2) L , and two scalars, also a doublet and a singlet of SU(2 ...

Phenomenology of Higgs bosons in inverse seesaw model with Type-X two Higgs doublet at the LHC
Journal of High Energy Physics, 2019 Type-X two Higgs doublet model is known to explain the muon g − 2 anomaly with a relatively light charged Higgs boson at large tan β. The light charged Higgs boson has been searched in the main τ ν mode at the colliders.
