Abstract
The masses of uudds¯, uuddd¯, and uussd¯ pentaquarks are evaluated in the framework of both the Effective Hamiltonian approach to QCD and spinless Salpeter equation using the Jaffe-Wilczek diquark approximation and the string interaction for the diquark-diquark-antiquark system. The masses of the light pentaquarks are found to be in the region above 2 GeV. Similar calculations yield the mass of [ud]2c¯ pentaquark ⼠3250 MeV and [ud]2b¯ pentaquark ⼠6509 MeV.
