b Physics Beyond the Standard Model [PDF]

, 2002
I review the signals for New Physics in CP-violating measurements in B and Lambda_b decays. I also discuss ways of identifying this New Physics, should such a signal be found.Comment: 10 pages, LaTeX, 1 figure, ps file included.

Physics beyond the Standard Model [PDF]

AIP Conference Proceedings, 1996
We discuss some of the signatures associated with extensions of the Standard Model related to the neutrino and electroweak symmetry breaking sectors, with and without supersymmetry. The topics include a basic discussion of the theory of neutrino mass and the corresponding extensions of the Standard Model that incorporate massive neutrinos; an overview ...

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 ...

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 ...

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.

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 ...

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

Lowering the scale of Pati-Salam breaking through seesaw mixing

Journal of High Energy Physics, 2021
We analyse the experimental limits on the breaking scale of Pati-Salam extensions of the Standard Model. These arise from the experimental limits on rare-meson decay processes mediated at tree-level by the vector leptoquark in the model.

Higgs: Standard Model and Beyond

, 2002
In this talk, I will discuss possible new physics effects that modify the interaction of Higgs boson(s) with top and bottom quarks, and discuss how to detect such effects in current and future high energy colliders.Comment: LaTeX, 8 pages including 1 ...
