Searching a systematics for nonfactorizable contributions to hadronic decays of D and D mesons

چکیده
We investigate nonfactorizable contributions to charm meson decays in D → K̄π/ K̄ρ /K̄π / K̄a1 / K̄ρ modes. Obtaining the contributions from spectator-quark diagrams for Nc = 3, we determine nonfactorizable isospin 1/2 and 3/2 amplitudes required to explain the data for these modes. We observe that ratio of these amplitudes seem to follow a universal value.

متن کاملNonfactorizable Contributions to Hadronic Matrix Elements by Use of Twist Wave Functions
A general approach for evaluating the nonfactorizable contributions to the hadronic matrix elements is described in terms of the higher twist wave functions of the mesons. An example is illustrated for the B → ππ decays. Supported in part by the US Department of Energy under contract DOE/ER/01545. The factorization approximation has conventionaly been used to describe the two-body nonleptonic d...
متن کاملHadronic Weak Decays of Heavy Mesons and Nonfactorization
The parameters χ1,2, which measure nonfactorizable soft gluon contributions to hadronic weak decays of mesons, are updated by extracting them from the data of D, B → PP, V P decays (P : pseudoscalar meson, V : vector meson). It is found that χ2 ranges from −0.36 to −0.60 in the decays from D → K̄π to D+ → φπ+, D → K̄π, while it is of order 10% with a positive sign in B → ψK, Dπ, Dπ, Dρ decays. Th...

We investigate nonfactorizable contributions to ππ → D decay modes. We perform isospin analysis of the nonfactorizable contributions to these decays. Obtaining the factorizable contributions from spectator-quark diagrams using 3 = C N , we determine nonfactorizable amplitudes for these decays and predict their branching ratios. Keywords—Mesons, Branching Ratios, Decay Amplitudes, Heavy Flavor M...

We investigate nonfactorizable contributions to two-body hadronic decays of the charmed mesons to a pseudoscalar meson and a vector meson in Cabibbofavored mode. Employing SU(3)-flavor symmetry for the nonfactorizable matrix elements, we obtain branching ratios of the decays in consistent agreement with experiment. PACS numbers: 13.25. m, 14.40. Cs, 14.40.Jz.
