Polarization and CP asymmetries in the decays B→K∗ψ, K∗ω, and K∗ϱ

Abstract We calculate branching ratios, polarization and CP asymmetries for the final exclusive states K ∗ ψ, K ∗ ω, K ∗ ϱ , make comparisons with experimental data, and suggest further tests of the underlying theoretical framework.

Parton model for inclusive semileptonic B meson decays

The parton model for semileptonic B meson decays is studied with special attention to the decay distributions. We find that the spectra show dramatic variations when we introduce cuts on the hadronic energy or invariant mass of hadrons. Results for both

decays are presented. The detailed spectra may help to separate the two types of decays.Abstract The parton model for inclusive semileptonic B decays is developed and compared with the results of heavy quark effective theory (HQET) and other methods for calculating lepton spectra. A distribution function, taken from production experiments, is used to describe the matrix elements of the dominant bilocal operator. The parton model gives an electron spectrum which is in excellent agreement with experiment at all measured electron energies and is well behaved at the endpoint where it may serve as a useful model. Moreover, it allows the calculation of additional spectra in several variables, which are computed and shown to vary strongly with the hadronic energy.

Searching for rephase-invariant CP- and CPT-violating observables in meson decays

Abstract We present a general model-independent and rephase-invariant formalism that cleanly relates observables to the fundamental parameters and explicitly separates different types of CP violation in the B 0 -, D 0 - and K 0 - systems. We emphasize its importance when interpreting experimental measurement of CP violation, the unitarity triangle, and probes of new physics.

Momentum distribution in the decay B{r_arrow}J/{psi}+X

We study the exclusive semileptonicD meson decaysD→K+π+l+ν. For this we develop the general formalism for the joint angular distribution of the charged lepton and theK meson and calculate the helicity dependent decay widths which determine the full angular distribution for several models withK*(892) andK0*(1430) intermediate state with nonresonant background terms calculated from chiral Lagrangians.

The decay B → Dπℓν using chiral and heavy quark symmetry

Abstract A vacuum gauge field Aμa for Yang-Mills theory is constructed; this field (i) is pure vacuum (Aμa=0) at the origin, (ii) approaches at large distances, the Belavin-Polyakov-Schwartz-Tyupkin pseudoparticle, and (iii) satisfies ∂μAμa=0 everywhere. The net topological charge is zero, and there is a Dirac-like string terminating at the origin.

A chiral anomaly channel in τ-decay. II

Abstract The decays ψ ′ → ψππ and ψ → ωϵ are studied in the framework of Zweig Rule violation via SU(4) pole dominance. The SU(3) character of the decay of the ψ is discussed in the same model. Using results of the purely hadronic decays, the cascade transition rates ψ ′ → ϵ c + γ and ϵ c ar ψ + γ are calculated and compared to recent experimental data.
