Diquarks, Pentaquarks and Dibaryons
Shi-Lin Zhu
Abstract
We explore the connection between pentaquarks and dibaryons composed of three diquarks in the framework of the diquark model. With the available experimental data on H dibaryon, we estimate the Pauli blocking and annihilation effects and constrain the P=- pentaquark SU(3)F singlet mass. Using the Θ+ pentaquark mass, we estimate P=- dibaryon mass.
