Octet baryon masses with two-gluon exchange effect

  • We report our investigation on the octet baryon spectrum in the nonrelativistic quark model by taking into account the two-gluon exchange effect. The calculated octet baryon masses agree better with the experimental data. It is also shown that the two-gluon exchange interactions bring a significant correction to the Gell-Mann−Okubo mass formula.

Octet baryon masses with two-gluon exchange effect

    Corresponding author: CHEN Yan,

Abstract: 

We report our investigation on the octet baryon spectrum in the nonrelativistic quark model by taking into account the two-gluon exchange effect. The calculated octet baryon masses agree better with the experimental data. It is also shown that the two-gluon exchange interactions bring a significant correction to the Gell-Mann−Okubo mass formula.
