Diquarks, Pentaquarks and Dibaryons

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 ${\Theta }^{+}$ pentaquark mass, we estimate $P=-$ dibaryon mass.
