We investigate the chiral mass splitting of parity-doubled J=0,1 states for c \bar{s} and c \bar{n} meson systems in the \tilde{U}(12)_{SF}-classification scheme of hadrons, using the linear sigma model to describe the light-quark pseudoscalar and scalar mesons together with the spontaneous breaking of chiral symmetry, and consequently predict the masses of as-yet-unobserved (0^{+},1^{+}) c \bar{n} mesons. We also mention some indications of their existence in the recent published data from the Belle and BABAR Collaborations.
