J/P=1/2+, J/P=3/2+ masses in statistical model

TL;DR

This paper develops mass formulae for J/P=1/2+ and J/P=3/2+ baryons using a statistical model that incorporates constituent quark masses, spin interactions, sea quark pairs, and gluons, matching experimental data.

Contribution

It introduces a statistical model-based approach to calculate baryon masses considering sea quark pairs and gluons, providing improved mass predictions.

Findings

Mass formulae match well with experimental data.

Inclusion of sea quark pairs and gluons improves mass estimates.

The model effectively predicts baryon masses for specified quantum states.

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 is estimated by the statistical model for J/P=1/2+, J/P=3/2+, incorporating the contributions from \sea" containing uu; dd; ss pairs and gluons . The measured masses are presented and found to be matching good with some of the experimental and theoretical data.
