Calculation of the s -wave final-state interactions in the N π π system

Kochkin

2005

Phys. Rev. D

The relativistic five-quark equations are found in the framework of the dispersion relation technique. The solutions of these equations using the method based on the extraction of the leading singularities of the amplitudes are obtained. The five-quark amplitudes for the low-lying pentaquarks including the u, d, s quarks are calculated. The poles of these amplitudes determine the masses of pentaquarks. The mass spectra of the isotensor pentaquarks with J P 1 2 ; 3 2 are calculated.

Heavy Baryonia With the Open and Hidden Charm

Matskevich

2013

Int. J. Mod. Phys. E

The relativistic six-quark equations are found in the framework of the dispersion relation technique. The strange baryonia are constructed without the mixing of the quarks and antiquarks. The relativistic six-quark amplitudes of the strange baryonia with the open and hidden strange are calculated. The poles of these amplitudes determine the masses of strange baryonia. 17 masses of baryonia are predicted.

Dibaryons With Two Heavy Quarks

Matskevich

2012

Int. J. Mod. Phys. E

The relativistic six-quark equations are constructed in the framework of the dispersion relation technique. The relativistic six-quark amplitudes of dibaryons including the light u, d and heavy c, b quarks are calculated. The approximate solutions of these equations using the method based on the extraction of leading singularities of the heavy hexaquark amplitudes are obtained. The poles of these amplitudes determine the masses of charmed and bottom dibaryons with the isospins I = 0, 1, 2 and the spin-parities J P = 0 + , 1 + , 2 + .
