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 ...

A long-lived stop with freeze-in and freeze-out dark matter in the hidden sector
Journal of High Energy Physics, 2020 In extended supersymmetric models with a hidden sector the lightest R-parity odd particle can reside in the hidden sector and act as dark matter. We consider the case when the hidden sector has ultraweak interactions with the visible sector.

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 ...

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 ...

Probing compressed dark sectors at 100 TeV in the dileptonic mono-Z channel
Journal of High Energy Physics, 2018 We examine the sensitivity at a future 100 TeV proton-proton collider to compressed dark sectors whose decay products are invisible due to below-threshold energies and/or small couplings to the Standard Model.

The Standard Model and Beyond [PDF]
AIP Conference Proceedings, 1986 This new edition of The Standard Model and Beyond presents an advanced introduction to the physics and formalism of the standard model and other non-abelian gauge theories. It provides a solid background for understanding supersymmetry, string theory, extra dimensions, dynamical symmetry breaking, and cosmology.

Global anomalies in the Standard Model(s) and beyond [PDF]
Journal of High Energy Physics, 2020 Abstract We analyse global anomalies and related constraints in the Standard Model (SM) and various Beyond the Standard Model (BSM) theories. We begin by considering four distinct, but equally valid, versions of the SM, in which the gauge group is taken to be G = GSM/Γn, with GSM = SU(3) × SU(2) × U(1) and Γn isomorphic to ℤ/n ...

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.
