Searching for charged lepton flavor violation at ep colliders
Journal of High Energy Physics, 2021 We investigate the sensitivity of electron-proton (ep) colliders for charged lepton flavor violation (cLFV) in an effective theory approach, considering a general effective Lagrangian for the conversion of an electron into a muon or a tau via the ...

Exploring properties of long-lived particles in inelastic dark matter models at Belle II
Journal of High Energy Physics, 2021 The inelastic dark matter model is one kind of popular models for the light dark matter (DM) below O(1) GeV. If the mass splitting between DM excited and ground states is small enough, the co-annihilation becomes the dominant channel for thermal relic ...

Stringy phenomenology with preon models [PDF]
Journal of High Energy Physics, Gravitation and Cosmology, 2024,
10, 1-7, 2023 We compare, following Pati, global symmetries our topological supersymmetric preon model with the heterotic E_8 x E_8 string theory. We include Pati's supergravity based preon model in this work and compare the preon interactions of his model to ours.

Journal of High Energy Physics, 2021 We explore the confinement-deconfinement phase transition (PT) of the first order (FO) arising in SU(N) pure Yang-Mills theory, based on Polyakov loop models (PLMs), in light of the induced gravitational wave (GW) spectra.

Journal of High Energy Physics, 2020 We propose a new method to extract D 0 − D ¯ $$ {D}^0-\overline{D} $$ 0 mixing parameters using the D 0 → K ¯ $$ \overline{K} $$ 0 π 0 decay with the K ¯ $$ \overline{K} $$ 0 reconstructed in the semileptonic mode.

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 ...

Cross-fertilising extra gauge boson searches at the LHC
Journal of High Energy Physics, 2021 For the purpose of cross-fertilising currently separate experimental approaches, we connect results of LHC analyses attempting to access the properties of additional W′ and Z′ bosons from Drell-Yan processes. Under theoretical assumptions linking the two

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 ...

Long-lived sterile neutrinos at the LHC in effective field theory
Journal of High Energy Physics, 2021 We study the prospects of a displaced-vertex search of sterile neutrinos at the Large Hadron Collider (LHC) in the framework of the neutrino-extended Standard Model Effective Field Theory (νSMEFT).

Mono-X versus direct searches: simplified models for dark matter at the LHC
Journal of High Energy Physics, 2017 We consider simplified models for dark matter (DM) at the LHC, focused on mono-Higgs, -Z or -b produced in the final state. Our primary purpose is to study the LHC reach of a relatively complete set of simplified models for these final states, while ...
