Understanding penta quark with various quark models
The pentaquark state recently discovered has been studied with three quark models which either fit the nucleon spin structure or the $NN$ scattering. A minimum $\Theta^+$ mass of 1620 MeV is obtained both for the ${1/2}^\pm$ state. The mixing of various color structure configurations, which would re...

| description | The pentaquark state recently discovered has been studied with three quark models which either fit the nucleon spin structure or the $NN$ scattering. A minimum $\Theta^+$ mass of 1620 MeV is obtained both for the ${1/2}^\pm$ state. The mixing of various color structure configurations, which would reduce the mass of the penta-quark state, should be taking into account in the calculation of penta-quark mass. |

The mixing of various color structure configurations, which would reduce the mass of the penta-quark state, should be taking into account in the calculation of penta-quark mass.We study the recently reported pentaquark state with three quark models which fit either nucleon spin structure or NN scattering data. The minimum Θ+ mass obtained is 1620 MeV for both the 12± states. The mixing of various color structure configurations, which could further reduce the mass of the pentaquark state, should be taken into account in further calculations.hep-ph/0408176oai:cds.cern.ch:7889032004 |
