In strong dynamical schemes for electroweak symmetry breaking the third generation must be treated in a special manner, owing to the heavy top quark. This potentially leads to new flavor physics involving the members of the third generation in concert with the adjoining generations, with potential novel effects in beauty and charm physics. We give a general discussion and formulation of this kind of physics, abstracted largely from Topcolor models which we elaborate in detail. We identify sensitive channels for such new physics accessible to current and future experiments.
We propose a model of spontaneous CP violation to address the strong CP problem in warped extra dimensions that relies on sequestering flavor and CP violation. We assume that brane-localized Higgs Yukawa interactions respect a U(3) flavor symmetry th
Within the Standard model with the 4th generation quarks b and t we have analyzed CP-violating flavor changing neutral current processes t -> cX; b-> sX, b-> bX,t-> cX, and t-> tX, with X=Z,H,gamma,g, by constructing and employing global, unique fit
The GIM Mechanism was introduced by Sheldon L. Glashow, John Iliopoulos and Luciano Maiani in 1970, to explain the suppression of Delta S=1, 2 neutral current processes and is an important element of the unified theories of the weak and electromagnet
We explore how to protect extra dimensional models from large flavor changing neutral currents by using bulk and brane flavor symmetries. We show that a GIM mechanism can be built in to warped space models such as Randall-Sundrum or composite Higgs m
New-physics (NP) constraints on first-generation quark-lepton interactions are particularly interesting given the large number of complementary processes and observables that have been measured. Recently, first hints for such NP effects have been obs
