The Pentaquark and the Pauli Exclusion Principle

Authors: Syed Afsar Abbas

A subtle but very real difference in how the Pauli Exclusion Principle is applicable to baryons in three-quark systems and to those in multiquark systems is presented. This distinction creates no important physical manifestations for structures with light quarks, as in case of the SU(3)-flavour group with (u,d,s)-quarks. However it does produce significant effects for multiquark systems containing one or more heavy quarks like the c- and b-quarks. In fact, these consequences permit us to comprehend the structure of the two pentaquark states at 4.38 and 4.45 Gev, which were discovered recently by the LHCb Collaboration at CERN. This model makes a unique prediction of the existence of similar two new pentaquarks with structure (uudb$\bar{b}$) and with similar spin assignments as above.
