  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.
