چکیده
We suggest a new technique to determine the CKM phase γ without neglecting the (soft) final state rescattering effects. We use (time integrated) B meson decay rates to π's and K's. A set of 5 ∆S = 0 (or 1 ∆S = 0 and 4 ∆S = 1) decay rates is used to compute the strong phases and magnitudes of the tree level and penguin contributions as functions of γ. These are used to predict a ∆S = 1 (∆S = 0) B d/s decay rate as a function of γ (using SU (3) symmetry). The measurement of this decay rate then gives γ. We illustrate this technique using different cases. Most of the decay modes we use are expected to be accessible at the B-factories (e + e − or hadron machines).

Flavordynamics chiral models of leptoquark fermions and bilepton gauge bosons with masses up to about 1 TeV, although coincident at low energy with the standard model, address the question of fermion mass hierarchy and explain the flavor question. The presence of charged right-handed weak currents coupled to bileptons, which we point out herein, is another remarkable feature of these chiral the...
