Description

The exact eigenenergies of the T4c, T4b, T2bc tetraquarks are calculated within the extended transitional Hamiltonian approach. The IBM, as proposed by Arima and Iachello [1], includes two types of bosons with angular momentum L = 0 (s bosons) and L = 2 (d bosons). To investigate the properties of tetraquarks, similar to that of the two-level system, a four-level system is considered here. To analyze the Quantum Phase Transition between the spherical and rotational limits, similar to Refs. [3-5], the SU(1,1) pairing algebra is introduced. Our results suggest that the pairing strengths are large enough to provide binding; an extended comparison with the current literature is also performed.
