Flavor Changing Effects in Family Nonuniversal Z ′ Models
Abstract Flavor-changing and CP -violating interactions of Z ′ to fermions are generally present in models with extra U(1) gauge symmetry that are string-inspired or related to broken gauged family symmetry. We study the consequences of such couplings in fermion electric dipole moments, muon g − 2, and K and B meson mixings. From experimental limits or measured values, we constrain the off-diag...
متن کاملFlavor Changing Neutral Currents and the Third Family
We consider a Two Higgs Doublet Model with Flavor Changing Scalar Neutral Currents arising at the tree level. All the most important constraints are taken into account and the compatibility with the present Electroweak measurements is examined. The Flavor Changing couplings involving the third family are not constrained to be very small and this allows us to predict some interesting signals of ...
متن کاملNew Flavor Changing Interactions in Extended Gauge Models
A new class of flavor changing (FC) neutral interactions can arise in models based on extended gauge groups (rank >4) when new charged fermions are present together with new neutral gauge bosons. In some cases the FC couplings to a new Z1 are expected to be sizeable, implying that the Z1 mass must be large enough as to explain the observed suppression of FC transitions. Concentrating on E6 mode...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Flavor-changing scalar interactions.
The smallness of fermion masses and mixing angles has recently been been attributed to approximate global U(1) symmetries, one for each fermion type. The parameters associated with these symmetry breakings are estimated here directly from observed masses and mixing angles. It turns out that although flavor changing reaction rates may be acceptably small in electroweak theories with several scal...
