Higgs couplings beyond the Standard Model [PDF]
, 2013 We consider the Higgs boson decay processes and its production, and provide a parameterisation tailored for testing models of new physics beyond the Standard Model.

Physics beyond the standard model [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2000 The Standard Model is in good shape, apart possibly from g_μ- 2 and some niggling doubts about the electroweak data. Something like a Higgs boson is required to provide particle masses, but theorists are actively considering alternatives. The problems of flavour, unification and quantum gravity will require physics beyond the Standard Model, and ...

Probing new electroweak states via precision measurements at the LHC and future colliders
Journal of High Energy Physics, 2019 Several new physics scenarios, motivated e.g. by dark matter, feature new electroweakly charged states where the lightest particle in the multiplet is stable and neutral.

Chiral Dynamics beyond the Standard Model [PDF]
, 2006 The SM Lagrangian without physical scalars is rewritten as the LO of a Low-Energy Effective Theory invariant under a higher non linear symmetry S_{nat} \supset SU(2)_W \times U(1)_Y.

PRESYMMETRY BEYOND THE STANDARD MODEL [PDF]
Modern Physics Letters A, 2009 We go beyond the Standard Model guided by presymmetry, the discrete electroweak quark–lepton symmetry hidden by topological effects which explain quark fractional charges as in condensed matter physics. We show that partners of the particles of the Standard Model and the discrete symmetry associated with this partnership appear as manifestations of a ...

Dark matter blind spots at one-loop
Journal of High Energy Physics, 2019 We evaluate the impact of one-loop electroweak corrections to the spin-independent dark matter (DM) scattering cross-section with nucleons (σ SI), in models with a so-called blind spot for direct detection, where the leading-order prediction for the ...

CP Violation Beyond the Standard Model [PDF]
, 1996 We review CP violation in various extensions of the electroweak sector of the Standard Model. A particular emphasis is put on supersymmetric models. We describe the two CP problems of supersymmetry, concerning $d_N$ and $\epsilon_K$. We critically review

Indirect probe of electroweak-interacting particles with mono-lepton signatures at hadron colliders
Journal of High Energy Physics, 2019 Electroweak-interacting massive particles (EWIMPs) exist in a broad class of new physics models beyond the Standard Model. Searching for such particles is one of most primary goal at the LHC and future colliders.

Interference effects in dilepton resonance searches for Z′ bosons and dark matter mediators
Journal of High Energy Physics, 2020 New Z′ gauge bosons arise in many extensions of the Standard Model and predict resonances in the dilepton invariant mass spectrum. Searches for such resonances therefore provide important constraints on many models of new physics, but the resulting ...
