| Sea flavor content of octet baryons and intrinsic five-quark Fock states |
| C. S. An, B. Saghai |
| Sea quark contents of the octet baryons are investigated by employing an extended chiral constituent quark approach, which embodies higher Fock five-quark components in the baryons wave-functions. The well-known flavor asymmetry of the nucleon sea $\\bar{d}-\\bar{u}$, is used as input to predict the probabilities of $\\bar{u}$, $\\bar{d}$ and $\\bar{s}$ in the nucleon, $\\Lambda$, $\\Sigma$ and $\\Xi$ baryons, due to the intrinsic five-quark components in the baryons wave functions. |
