11 Jun 2003 | | Journal: | Phys.Lett. B567 (2003) 273-276 DOI: 10.1016/j.physletb.2003.06.050 | | Subject: | hep-ph hep-ex nucl-ex nucl-th | | Abstract: | The recent discovery of a narrow resonance in the decay $J/psi o gamma p ar{p}$ is described as a zero baryon number, ``deuteron-like singlet ${}^1S_0 $’’ state. The difference in binding energy of the deuteron (-2.225 MeV) and of the new state (-17.5 MeV) can be accounted for in a simple potential model with a $lambda cdot lambda$ confining interaction. | | Source: | arXiv, hep-ph/0306097 | | Services: | Forum | Review | PDF | Favorites | |
