Magnetic moments of S-shell pentaquarks in the constituent quark model
Abstract
We discuss the magnetic moments of the recently discovered exotic baryons Theta(+) and Xi(--) and their multiplet partners in the framework of a naive additive quark model. These baryons are set up as pentaquark states where four quarks and a single antiquark are located in their ground state orbit. The pentaquark states are classified as members of the flavor SU(3) octet and antidecuplet with spin-parity JP = (1/2)- and (3/2)-, where we determine the magnetic moments of these pentaquark states.
