Abstract

We propose that there coexist two scalar mesons of different structures (the conventional ^3P_0 {cn^^-} meson and a scalar four-quark [cn][u^^-d^^-] meson) in the recently observed broad bumps just below the large peak of the tensor meson in the Dπ mass distribution. We base this proposal on the interpretation of the D^+_<s0>(2317) as a [cn][s^^-n^^-] four-quark meson. The strange counterparts of these scalar mesons are also studied.
