Discovery of Long-lived Pentaquarks and Decay Modes of Heavy Quarks Part I

This article presents a new technique for discovering long-lived pentaquarks and provides tables of long-lived states and decay modes of hadrons constructed with one or more heavy quarks. It discusses the effective Hamiltonian approach in QCD and predicts masses of undiscovered doubly heavy baryons.

With only two parameters: the string tension sigma and the strong coupling constant alpha_s we obtain a good description of the ground state light and heavy baryons. The prediction of masses of the doubly heavy baryons not discovered yet are also given. In particular, a mass of 3620 MeV for the lightest (ccu) baryon is found by employing the hyperspherical formalism to the
