We propose that there coexist two scalar mesons of different structures (aconventional meson and a four-quark meson) in the recently observed broad bumpsjust below the large peak of the tensor meson in the D-pi mass distribution. Webase this proposal on the interpretation of the charm-strange scalar meson ofmass 2317 MeV as a four-quark meson. The strange counterparts of these scalarmesons are also studied.Comment: 4 pages, 0 figures, Revte
