- W1982944560 abstract "Abstract The assumption of a narrow (Γ ∼ 5 MeV) dibaryon-resonance with quantum numbers J P =0 − , T=0 and a mass of 2065 MeV allowed recently to describe all pionic double charge exchange cross-sections for various nuclei [1]. We investigate the mass of a 6-quark state with these quantum numbers in the framework of the nonrelativistic constituent quark model. Our shell-model diagonalisation including a large basis of excited states results in masses in the range of 2500 MeV. Since this result depends strongly on the explicit form of the confining potential, we cannot exclude the existence of the proposed dibaryon. For example the usual assumption of a quark-quark pair-confinement mechanism might not be valid in the 6q-system." @default.
