Abstract

The mass formulae for the baryon octet and decuplet are calculated. These formulae are function of constituent quark masses and spin-spin interaction terms for the quarks inside the baryons. The coefficients in the mass formulae are estimated by the statistical model for $Mathematical equation: $J^{P}=1/2^{+},3/2^{+}$$ , incorporating the contributions from the “sea” containing $Mathematical equation: $u\overline{u}$$ , $Mathematical equation: $d\overline{d}$$ , $Mathematical equation: $s\overline{s}$$ pairs and gluons. The measured masses are presented and found to be matching well with some of the experimental and theoretical data.
