THE qq̄ S - WAVE AXIAL - VECTOR MESONS IN THE COVARIANT Ũ ( 12 ) - SCHEME

چکیده
We study the properties of axial vector mesons a1 and b1 as relativistic S-wave states which are predicted in the Ũ(12)-scheme, through the analyses of their radiative and pionic decays. Specifically, partial widths of the strong a1(b1) → ρ(ω)π processes, their D/S-wave amplitude ratios, and radiative transition widths of a1(b1) → πγ processes are calculated by using a simple decay interaction model, and made a comparison with the respective experimental values.

Recently the Ũ(12) level-classification scheme of hadrons1) has been proposed, which is a covariant generalization of non-relativistic scheme based on SU(6)SF . In the Ũ(12)-classification scheme a new type of relativistic states, called chiral states, which have no correspondents in the non-relativistic scheme, are expected to exist in lower mass region for light quark systems. Especially the ...
متن کاملCovariant Classification of qq̄-Meson Systems and Existence of New Scalar and Axial-Vector Mesons
The level classification of quark-antiquark systems is generally made by the LScoupling scheme, resorting to the non-relativistic quark model. However, it has been well known that the π-meson with the (L,S) = (0, 0) shows also the properties as a Nambu-Goldstone boson in the case of spontaneous breaking of a relativistic symmetry, the chiral symmetry. In this talk I present a covariant classifi...
متن کاملThe Ũ(12)-Classification Scheme, Static U(4)-Spin Symmetry for Light-Quarks and “Exotic” Hadrons
Several years ago we have proposed a manifestly covariant Ũ(12)SF -classification scheme of hadrons, which maintains the successful SU(6)SF ⊗O(3)L framework in Non-Relativistic Quark Model and is also reconcilable with the mechanism of Spontaneously-Broken Chiral Symmetry in Relativistic Field Theoretical Models. The essential point here is to notice the overlooked freedom of the SU(2)ρ-spin fo...

Abstract. The Nijmegen Unitarized Meson Model and its application to scalar mesons is briefly revisited. It is shown that all scalar states up to 1.5 GeV can be described as 3P0 qq̄ states coupled to the OZI-allowed open and closed two-meson channels consisting of pseudoscalar and vector mesons. Crucial are the manifestation of a resonancedoubling phenomenon, typical for strong S-wave decay, and...

The covariant level-classification scheme of hadrons with Ũ(12)SF ⊗ O(3, 1)L symmetry has been proposed, 1) which gives a covariant quark representation for composite hadrons with definite Lorentz and chiral transformation properties. This covariant classification scheme unifies two seemingly contradictory viewpoints, nonrelativistic and extremely relativistic ones, of quark-model classificatio...
