نویسنده
چکیده
We analyze the direct detection rate of minimal supersymmetric neutralino dark matter in germanium, sapphire and sodium iodide detectors, imposing cosmological and accelerator bounds including those from b → sγ decay. In contrast with several other recent analyses we find models with light charged higgsinos and large stop mixing in which the counting rate in solid state detectors exceeds 10 events/kg/day.

An introduction to the methods and ideas of Chiral Perturbation Theory is presented in this talk. The discussion is illustrated with some phenomenological predictions that can be compared with available experimental results.

We discuss the electromagnetic-penguin-dominated radiative B decays B → X s + γ, B ±(0) → K * ±(0) + γ, and B s → φ + γ in the context of the standard model (SM) and their Cabibbo-Kobayashi-Maskawa (CKM)-* 0 + γ, using QCD sum rules for the exclusive decays. The importance of these decays in determining the parameters of the CKM matrix [1] is emphasized. The semileptonic decays B → X s ℓ + ℓ − ...

Integrability of the Wess–Zumino–Witten model as a non–ultralocal theory * Abstract We consider the 2–dimensional Wess–Zumino–Witten (WZW) model in the canon-ical formalism introduced in [5]. Using an r–s matrix approach to non–ultralocal field theories we find the Poisson algebra of monodromy matrices and of conserved quantities with a new, non–

We explore several supersymmetric alternatives to explain predictions for the cosmic ray positron excess. Light sneutrino or neutralino LSP’s, and a fine-tuned model designed to provide a δ-function input, can give adequate statistical descriptions of the reported HEAT data if non-thermal production of the relic cold dark matter density dominates and/or if “boost factors”(that could originate i...

The decays B+ → D∗+ s γ and B+ → D∗+γ can be used for an extraction of |Vub|. When the b and c quarks are nearly degenerate the rate for these modes can be determined in terms of other observed rates, namely BB mixing and D → Dγ decay. To this end we introduce a novel application of heavy quark and flavor symmetries. Although somewhat unrealistic, this limit provides us with a first estimate of...
