String goniometry by neutral currents

Flavour-Changing Neutral Currents

In this paper we will present the theory of Flavour-Changing Neutral Currents and the possible implications for the discovery of new particles. We also present a search for such currents in decays of B s → μ+μ− and B → μ+μ− , which has direct implications for the constraints of new theories, especially Supersymmetry.

Flavor Changing Neutral Currents

A study of Rb and Rc is presented in the context of a Two Higgs Doublet Model (2HDM) with flavor changing scalar currents (FCSC). Implications of the model for the ρ-parameter and for b → sγ are also considered. The experimental data on Rb places stringent constraints on the model parameters. The configuration of the model needed to account for Rb is found to be irreconcilable with constraints ...

WEAK NEUTRAL CURRENTS IN e + -

The differential cross section of e+e--) F+F(F+=p+, p, 1;‘, etc.) is calculated for arbitrarily polarized incident and outgoing beams by exchanging one photon and one neutral Z-meson coupled to neutral weak currents. The interference effects manifest themselves in significant parity violating asymmetries for longitudinal polarizations which are about 4(4.5)0/o at q=28 GeV, 9(12.5)% at q=40 GeV ...

Neutrino Flavor Goniometry by High Energy Astrophysical Beams

It is shown how high energy neutrino beams from very distant sources can be utilized to learn about many properties of neutrinos such as lifetimes, mass hierarchy, mixing, minuscule pseudo-Dirac mass splittings and other exotic properties; in addition, the production mechanism of neutrinos in astrophysical sources can also be elucidated.
