Hybrid Quark Model and Six-Quark Probability

Abstract

In the hybrid quark model (HQM), when the distance between the two nucleons is greater than a certain cut off radius, they maintain their identity as nucleons but when the distances between the two baryons is smaller than a certain cut off radius, then the baryons overlap to form a six-quark bag. The fact that the probability to find six-quark for  does not have to be the same as that of finding two nucleons for  can be accommodated either by allowing for a different normalization of the external wave function or by modifying the potential for . The mathematical framework for the evaluation of six-quark probability for nucleon-nucleon pair inside a nucleus or a hypernucleus from the shell model wave functions for the evaluation of matrix elements in the overlap probability has been compared.
