Stable Heavy Pentaquark States
arXiv:hep-ph/0402076 · doi:10.1016/j.physletb.2004.03.087
Abstract
If the Theta^+(1540) is interpreted as a bound state of a quark and two (ud) diquarks in a relative P-wave, then it is very likely that there exist pentaquark states with a heavy antiquark, or , and two ``light'' diquarks in a relative S-wave which are stable against strong decays. We make a mass estimate for exotic states of this type and discuss their weak decays. Isospin relations are constructed which test their flavor quantum numbers.
