Introduction to Supersymmetry: Astrophysical and Phenomenological Constraints
These lectures contain an introduction to supersymmetric theories and the minimal supersymmetric standard model. Phenomenological and cosmological consequences of supersymmetry are also discussed. Based on lectures delivered at the Les Houches Summer School, July 1999
متن کاملPhenomenological Constraints on Patterns of Supersymmetry Breaking
Specific models of supersymmetry breaking predict relations between the trilinear and bilinear soft supersymmetry breaking parameters A0 and B0 at the input scale. In such models, the value of tan β can be calculated as a function of the scalar masses m0 and the gaugino masses m1/2, which we assume to be universal. The experimental constraints on sparticle and Higgs masses, b → sγ decay and the...
متن کاملPhenomenological Constraints on Extra-Dimensional Scalars
We examine whether the ATLAS detector has sensitivity to extradimensional scalars (as opposed to components of higher-dimensional tensors which look like 4D scalars), in scenarios having the extra-dimensional Planck scale in the TeV range and n ≥ 2 nonwarped extra dimensions. Such scalars appear as partners of the graviton in virtually all higher-dimensional supersymmetric theories. Using the s...
متن کاملA survey of phenomenological constraints on supergravity models
We advocate the study of supergravity models as well motivated few-parameter low-energy supersymmetric models. In this context we survey a broad range of phenomenological constraints and future tests, including present and nearfuture Tevatron (q̃, g̃, χ±1 , t̃1) and LEP (h, χ ± 1 ) mass limits, collider indirect tests (Γ Z , Rb,mt), rare processes (b → sγ, (g− 2)μ), proton decay, and dark matter (...
متن کاملB → τ + τ − ( X ) decays : first constraints and phenomenological implications
The study of B → τ τ (X) decays can provide us with a better understanding of the third generation, and can be a useful probe of physics beyond the standard model. We present a model independent analysis of these decays. We classify new physics that can largely enhance the decay rates and we discuss the constraints implied by other processes. Experimentally, flavor changing neutral current B de...
