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 ...

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.

Higgs couplings beyond the standard model [PDF]
Journal of High Energy Physics, 2013 Abstract 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. We also compare our formalism to other existing parameterisations based on scaling factors in front of the couplings and to effective Lagrangian approaches ...

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 ...

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.

Testing the standard model and beyond [PDF]
AIP Conference Proceedings, 1998 This paper is based on lectures presented to mathematical physicists and attempts to provide an overview of the present status of the Standard Model, its experimental tests, phenomenological and experimental motivations for going beyond the Standard Model via supersymmetry and grand unification, and ways to test these ideas with particle accelerators.

Neutrino in standard model and beyond [PDF]
Physics of Particles and Nuclei, 2015 After discovery of the Higgs boson at CERN the Standard Model acquired a status of the theory of the elementary particles in the electroweak range (up to about 300 GeV). What general conclusions can be inferred from the Standard Model? It looks that the Standard Model teaches us that in the framework of such general principles as local gauge symmetry ...

Monte Carlo simulations of physics beyond the standard model [PDF]
, 2008 The Large Hadron Collider, currently under construction at CERN, will give direct access to physics at the TeV scale for the first time. The lack of certainty over the type of physics that will be revealed has produced a wealth of ideas for so-called ...

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 ...
