We show, using the same Lagrangian for the K1(1270)→πK0⁎(1430) and K0⁎(1430)→K1(1270)π decays, that the present PDG data on the partial decay width of K1(1270)→πK0⁎(1430) implies a width for K0⁎(1430)→K1(1270)π decay which is about one order of magnitude larger than the total K0⁎(1430) width. A discussion on this inconsistency is done, stressing its relationship to the existence of two K1(1270) states obtained with the chiral unitary theory, which are not considered in the experimental analyses of Kππ data. |
