Diquarks, pentaquarks, and dibaryons

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 $H$ we estimate the Pauli blocking and annihilation effects and constrain the $P=-\text{pentaquark}SU{\left(3\right)}_F$ singlet mass. Using the ${\Theta }^{+}$ pentaquark mass, we estimate $P=-\text{dibaryon}\text{mass}$
