| dc.description | The radiative transitions between ground-states (GS) of light q bar q mesons are investigated in the 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 -> P gamma process are well reproduced, and furthermore, the predicted width of b_{1}(1235) -> pi gamma process (Gamma_{theor}=229 keV), by assigning b_{1}(1235) as a member of the {}^{3}S_{1} chiral states A^{(E)}, is in good agreement with experimental one (Gamma_{exp} =230 +- 60 keV). From this results it is indicated that b_{1}(1235) meson, classified as {}^{1}P_{1} state in conventional non-relativistic (NR) classification scheme, is a good candidate of chiral state in the 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. | |
