A Relativistic Description of Hadronic Decays of the Meson Π 1
نویسنده
چکیده
The subject of this work is analysis of hadronic decays of exotic meson π1 in a fully relativistic formalism, and comparison with the nonrelativistic results. The relativistic spin wave functions of mesons and hybrids are constructed based on unitary representations of the Lorentz group. The radial wave functions are obtained from phenomenological considerations of the mass operator. We find that decay channels π1 → πb1 and π1 → πf1 are favored, in agreement with results obtained using other models, thus indicating some model independence of the S + P selection rules. We will also report on effects of meson final state interactions in exotic channels.

In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...

Nikodem J. Pop lawski A Relativistic Description of Hadronic Decays of the Exotic Meson π1 Exotic mesons are striking predictions of quantum chromodynamics that go beyond the quark model. They can provide great insight into understanding phenomena such as asymptotic freedom, confinement, and dynamical symmetry breaking. This work analyzes hadronic decays of exotic mesons, with a focus on the li...

We evaluate the form factors describing the semileptonic decays B0 → J/ψ (ηc)D lν̄l, within the framework of a QCD relativistic potential model. This decay is complementary to B0 → J/ψ (ηc) D+ π− in a phase space region where a pion factors out. We estimate the branching ratio for these semileptonic and nonleptonic channels, finding BR(B0 → J/ψ (ηc) D+ l νl) ≃ 10−13, BR(B0 → J/ψ D+ π−) = 3.1 × 1...

Abstract The two-particle hadronic decays of B c meson into S-wave and P-wave charmonium states X c¯ c are considered in the framework of hard gluon exchange model. It is shown that decay width of B c meson into P-wave charmonium states exceeds one for S-wave states. In compare with the previous estimations we predict the enhancement by factor ∼ 2 the b...
