Helicity and partial wave amplitude analysis of D -> K^* ρdecay
El hassan El aaoud, A. N. Kamal
We have carried out an analysis of helicity and partial-wave amplitudes for the process D -> K^* ρin the factorization approximation using several models for the form factors. All…
Resonant final-state interactions in D^0 -> \bar{K}^{0} η, \bar{K}^{0} η' Decay
El aaoud El hassan, A. N. Kamal
We have investimated the effect of the isospin 1/2, J^P = 0^+ resonant state K^*_0(1950) on the decays D^0 ->\bar{K}^{0}ηand D^0 ->\bar{K}^0 η' as a function of the branching ratio…

Using NLL values for Wilson coefficients and including the contributions from the penguin diagrams, we estimate the amount of nonfactorization in two-body hadronic B decays. Also,…

F. M. Al-Shamali, A. N. Kamal
We assume universal values for the color-singlet () and color octet () nonfactorization parameters in B Decays. Two sets of color-favored processes and one set of color-s…
scattering phase shifts and CP violation in decay

CP-violating signals in weak decay require the knowledge of - and -wave scattering phases at center-of-mass energy. We have calculated these phases in…

A. N. Kamal, C. W. Luo
The role of inelastic final-state interactions in CP asymmetries and branching ratios is investigated in certain chosen single isospin two-body hadronic B decays. Treating final-st…

Available experimental data on decay rates for B --> ψK, and decay rates and transversity amplitudes for B --> ψK^* are used to investigate nonfactorization contributions in these…

A. N. Kamal, C. W. Luo
The role of inelastic final state interactions in CP asymmetries is investigated in single isospin two-body hadronic decays of the B meson. We demonstrate that in a channel where t…
Direct CP Violation Asymmetries in Exclusive B Decays in a Bethe-Salpeter Approach
A. N. Kamal, C. W. Luo
CP asymmetry in some exclusive decays of charged B meson are calculated in a Bethe-Salpeter approach. Hadronic final state interactions are ignored. Complex decay amplitudes are as…

Failure of the commonly used B -> K(K^*) form factors in explaining recent data on B -> J/Ψ+ K ( K^* ) decays
M. Gourdin, A. N. Kamal, X. Y. Pham
We establish restrictions on $B \ra K ( K^* )$ form factors imposed by recent data on $B \ra J/Ψ+ K ( K^* ) $ decay rates and polarization. We show that these constraints are not s…
