A Relativistic Description of Hadronic Decays of the Meson π₁
Poplawski, Nikodem J.
Original · EN
The subject of this work is the analysis of hadronic decays of the 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 the decay channels πb₁ and πf₁ are favored, in agreement with the results obtained using other models, thus indicating some model independence of the S+P selection rules.
