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 ...

Exclusive Λb→Λℓ+ℓ− decay beyond standard model
, 2003 Using the most general, model independent form of the effective Hamiltonian, the exclusive rare baryonic Λb→Λℓ+ℓ−(ℓ=μ,τ) decay is analyzed. We study the sensitivity of the branching ratio and lepton forward–backward asymmetry to the new Wilson ...

Status of the Standard Model and beyond [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2004 We present a concise review of the status of the Standard Model and of the search for new physics.

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.

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.

Beyond the standard model with the LHC [PDF]
Nature, 2007 Whether or not the Large Hadron Collider reveals the long-awaited Higgs particle, it is likely to lead to discoveries that add to, or challenge, the standard model of particle physics. Data produced will be pored over for any evidence of supersymmetric partners for the existing denizens of the particle 'zoo' and for the curled-up extra dimensions ...

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 ...
