Open AccessInterplay of inert doublet and vector-like lepton triplet with displaced vertices at the LHC/FCC and MATHUSLA
We study the interaction between the inert Higgs doublet (IDM) dark matter and a vector-like SU(2) triplet lepton (VLL), both of which are Z2-odd. The vector current of the VLL with the Z-boson rules out a fermio...

Open AccessA novel search strategy for right-handed charged gauge bosons at the Large Hadron Collider
We explore the potential of the Large Hadron Collider (LHC) in detecting a signal originating from the production of a heavy SU(2)R charged gauge boson that then decays into a top-bottom quark pair via the mediat...

Open AccessReconciling collider signals, dark matter, and the muon anomalous magnetic moment in the supersymmetric U(1)R × U(1)B−L model
We study the low-scale predictions of the supersymmetric model extended by U(1)R × U(1)B−L symmetry, obtained by breaking SO(10) symmetry at GUT scale via a left-right supersymmetric model. Two new singlet Higgs ...

Open AccessDark matter in the Alternative Left Right model
The Alternative Left-Right Model is an attractive variation of the usual Left-Right Symmetric Model because it avoids flavour-changing neutral currents, thus allowing the additional Higgs bosons in the model t...

Open AccessVacuum structure of Alternative Left-Right Model
We investigate an Alternative Left-Right Model (ALRM) with SU(2)L as well as SU(2)R gauge groups, but unlike the traditional left-right symmetric models (LRSM) is not symmetric under the exchange of the fermion c...

Open AccessCross-fertilising extra gauge boson searches at the LHC
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. Und...

Open AccessElectron and muon magnetic moments and implications for dark matter and model characterisation in non-universal U(1)′ supersymmetric models
We attribute deviations of the muon and electron magnetic moments from the theoretical predictions to the presence of an additional U(1)′ supersymmetric model. We interpret the discrepancies between the muon a...

Evading Z′ boson mass limits in U(1)′ supersymmetric models
Supersymmetric models augmented by U(1)′ gauge symmetries resolve some of the outstanding problems in MSSM, such as the μ problem. Unfortunately collider phenomenology in such models is hindered by the stringent ...

Open AccessReinterpreting the results of the LHC with MadAnalysis 5: uncertainties and higher-luminosity estimates
The MadAnalysis 5 framework can be used to assess the potential of various LHC analyses for unraveling any specific new physics signal. We present an extension of the LHC reinterpretation capabilities of the prog...

Open AccessE6 motivated UMSSM confronts experimental data
We test E6 realisations of a generic U(1)′ extended Minimal Supersymmetric Standard Model (UMSSM), parametrised in terms of the mixing angle pertaining to the new U(1)′ sector, θ E 6 \( {\theta}_{E_6} \) ,...

Open AccessNatural dark matter and light bosons with an alternative left-right symmetry
We perform a consistent analysis of the alternative left-right symmetric model emerging from E6 grand unification. We include a large set of theoretical and experimental constraints, with a particular emphasis on...

Open AccessLoopholes in Z′ searches at the LHC: exploring supersymmetric and leptophobic scenarios
Searching for heavy vector bosons Z′, predicted in models inspired by Grand Unification Theories, is among the challenging objectives of the LHC. The ATLAS and CMS collaborations have looked for Z′ bosons assumin...

Open AccessResonant slepton production and right sneutrino dark matter in left-right supersymmetry
Right-handed sneutrinos are natural components of left-right symmetric supersymmetric models where the gauge sector is extended to include right-handed weak interactions. Unlike in other models where right-han...

Neutralino and chargino production in U(1)′ at the LHC
We examine the production and decay modes of neutralinos and charginos in a softly-broken supersymmetric model with an extra Abelian symmetry U(1)′. We perform the study in a U(1)′ model with a secluded sector, w...

Open AccessChargino and neutralino production at the Large Hadron Collider in left-right supersymmetric models
We present a complete and extensive analysis of associated chargino and neutralino production in the framework of a supersymmetric theory augmented by left-right symmetry. This model provides additional gaugin...

Mesons in the bag model
The spectra of vector- and pseudo-scalar mesons is considered in the M.I.T. Bag Model, incorporating recent improvements in the treatment of the pion and allowing for radially excited states. It is shown that ...
