چکیده
in the e U(12)-scheme. In this scheme the rich decay-spectra are offered even in transition between GS due to the appearance of chiral states. As a result the radiative decay widths of the ordinary V → Pγ process are well reproduced, and furthermore, the predicted width of b1(1235) → πγ process (Γtheor = 229 keV), by assigning b1(1235) as a member of the S1 chiral states A, is in good agreement with experimental one (Γexp = 230± 60 keV). From this results it is indicated that b1(1235) meson, classified as P1 state in conventional nonrelativistic (NR) classification scheme, is a good candidate of chiral state in the e U(12)-scheme. The other radiative transition widths of some chiral states are also predicted. Accordingly the predicted values given here, will provide useful insights in their search at BES.

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 ...

O(3, 1)L symmetry, the ground state baryons and antibaryons are assigned to the (12× 12× 12)Sym = 364-multiplet in the spin-flavor Ũ(12)SF symmetry. This multiplet includes, in addition to the ordinary 56-multiplet of the static SU(6)SF , the extra chiral 56 ′ and 70-multiplets, called “chiralons,” which are expected to exist with masses in 1 ∼ 2 GeV region. Their electro-magnetic properties, m...

We re-investigate the radiative charged kaon decay K → πeνeγ [K ± e3γ ] in chiral perturbation theory, merging the chiral expansion with Low’s theorem. We thoroughly analyze the precision of the predicted branching ratio relative to the non-radiative decay channel. Structure dependent terms and their impact on differential decay distributions are investigated in detail, and the possibility to s...

We investigate two specific Green functions in the framework of chiral perturbation theory. We show that, using analyticity and unitarity, their leading logarithmic singularities can be evaluated in the chiral limit to any desired order in the chiral expansion, with a modest calculational cost. The claim is illustrated with an evaluation of the leading logarithm for the scalar two–point functio...
