Multiquark states. III.Q6dibaryon resonances

Abstract

The mass spectrum for orbitally excited dibaryon resonances is predicted under the assumption of two clusters of quarks in a stretched bag. Decay mechanisms, stability, and experimental candidates in the $Y=2, 1, \mathrm{and} 0$ channels are discussed. Natural explanations are found for, e.g., the ${}_{}{}^3{}_{}{}^{}F_3^{}{}_{}{}^{}$ and ${}_{}{}^1{}_{}{}^{}D_2^{}{}_{}{}^{} \mathrm{pp}$ resonances, for the shoulder at 2.14 GeV, and the enhancement at 2.25 GeV in the $\Lambda p$ invariant-mass spectrum.
