In the covariant level‐classification scheme of hadrons proposed recently the existence of chiral scalar and axial‐vector mesons, as respective chiral partners of the pseudo‐scalar and vector mesons, were predicted in the ground states of Heavy‐Light meson systems. The narrow resonances DsJ(2317) and DsJ(2463), observed recently in the final states Ds π0 and Ds*+ π0 are to be assigned, respectively, as the scalar and axial‐vector chiral particles in the ground‐state ( cs̄ ) system. In this work we investigate the possibility of existence of the chiral axial‐vector ( cn̄ ) meson, , by re‐analyzing the experimental data presented recently by the Belle Collaboration.
