Is the D_sJ(2632) Meson a Cryptoexotic Tetraquark Baryonium State?


الملخص بالإنكليزية

We suggest that the recently discovered charm-strange meson D_sJ(2632), with unusual properties, could be a cyptoexotic tetraquark baryonium state cdd_bars_bar. We predict other four narrow states, as Regge recurrences of D_sJ(2632), below the possible baryon-antibaryon thresholds.
