AbstractAbstract
[en] In a covariant level-classification scheme of hadrons proposed recently, the existence of ''chiral particles'', scalar and axial-vector mesons as the partners of the ground-state pseudo-scalar and vector mesons, respectively, were predicted in D and B meson systems, realizing a linear representation of chiral symmetry concerning the light quarks. In this work we reanalyze the D*π mass spectra obtained through Υ(4S) and Z0 decay and the Bπ spectra obtained through Z0 decay to show the possibility of the existence of D1χ and B0χ, respectively. This talk is a review of essential points of our previous work. (author)
