New physics explanations of a μ in light of the FNAL muon g − 2 measurement
Journal of High Energy Physics, 2021 The Fermilab Muon g −2 experiment recently reported its first measurement of the anomalous magnetic moment a μ FNAL $$ {a}_{\mu}^{\mathrm{FNAL}} $$ , which is in full agreement with the previous BNL measurement and pushes the world average deviation ∆ a ...

BEYOND THE STANDARD MODEL [PDF]
High Energy Physics, 2007 Review of recent developments in attempts to go beyond the Standard Model is given. We concentrate on three main unresolved problems: mechanism of electroweak symmetry breaking, expected new physics at the TeV scale (mainly SUSY) and the origin of the Dark matter.

Searching for the Higgsino-Bino sector at the LHC
Journal of High Energy Physics, 2020 We study the search for electroweakinos at the 13 TeV LHC in the case of heavy scalar superpartners. We consider both the direct production mode and the one associated with the decay of heavy Higgs bosons, and concentrate on the case of light Higgsinos ...

Lepton flavor violating decays τ → Pl in the U(1) X SSM model
Journal of High Energy Physics, 2022 U(1) X SSM is the extension of the minimal supersymmetric standard model (MSSM) and its local gauge group is SU(3) C × SU(2) L × U(1) Y × U(1) X . To obtain this model, three singlet new Higgs superfields and right-handed neutrinos are added to MSSM.

Hunting wino and higgsino dark matter at the muon collider with disappearing tracks
Journal of High Energy Physics, 2021 We study the capabilities of a muon collider experiment to detect disappearing tracks originating when a heavy and electrically charged long-lived particle decays via X + → Y + Z 0, where X + and Z 0 are two almost mass degenerate new states and Y + is a

Journal of High Energy Physics, 2019 We point out that two models that reconcile the neutron lifetime anomaly via dark decays of the neutron, also predict dark matter-neutron ( χ ¯ $$ \overline{\chi} $$ − n) annihilation that may be observable in neutron-antineutron oscillation and proton ...

How heavy can neutralino dark matter be?
Journal of High Energy Physics, 2019 What is the upper limit of the mass of the neutralino dark matter whose thermal relic is consistent with the observation? If the neutralino dark matter and colored sparticles are extremely degenerated in mass, with a mass difference less than the QCD ...

Closing the window for compressed dark sectors with disappearing charged tracks
Journal of High Energy Physics, 2017 We investigate the sensitivity at current and future hadron colliders to a heavy electrically-charged particle with a proper decay length below a centimetre, whose decay products are invisible due to below-threshold energies and/or small couplings to the

Employing nucleon decay as a fingerprint of SUSY GUT models using SusyTCProton
Journal of High Energy Physics, 2021 While the observation of nucleon decay would be a smoking gun of Grand Unified Theories (GUTs) in general, the ratios between the decay rates of the various channels carry rich information about the specific GUT model realization.
