Study of Ground State Baryon JP=1/2+ Octet and JP=3/2+ Decuplet using Statistical methods.

Abstract

In this thesis, various low energy properties of ground state baryonic systems have been studied using the statistical model. Various properties like masses, magnetic moments, spin distribution, of spin 1/2+ octet and 3/2+ decuplet particles are analyzed in this work. This thesis is dedicated to some of the basic unanswered questions like role of sea (including ss) in determining properties of baryons to study internal structure of ground state baryons. The calculations are performed at the energy scale of 1GeV. Therefore, the importance of the strange quark contributions is explicitly studied in the present work. Here, baryonic structure is considered to be consisting of valence quarks and sea limited to a few number of quark-antiquark pairs multiconnected non perturbatively through gluons. Statistical model is used to find the answers of some of the queries by using the statistical techniques.
