Masses of tetraquark candidates D-S(+)(2317) and D-S(+)(2632) using Glozman-Riska hyperfine interaction
Апстракт
Using the Glozman-Riska (flavor-spin) interaction Hamiltonian and the SU(3) flavor symmetry breaking, we perform a schematic study of the masses of the scalar charmed tetraquarks in the following representations: (15) over bar (S), (3) over barS, 6(A) and (3) over bar (A). Obtained pattern indicates that D-S(+)(2317) is a four-quark state in the SU(3)(F) (3) over bar (A) representation. D-S(+) (2632) is identified with a state from mixing of the (15) over bar (S) and (3) over bar (S) representations. There are 27 different tetraquarks composed of a charm quark c and of the three light flavors u, d, s: 11 cryptoexotic (3 D-S(+), 4 D+, 4 D-0) and 16 explicit exotic states. The identification of D-S(+)(2317) and D-S(+)(2632) with two cryptoexotic states in tetraquark spectrum is possible when including Glozman-Riska hyperfine interaction. We also compare Glozman-Riska and Fermi-Breit contributions to the tetraquark masses and analyze the corresponding tetaraquark mass spectra. (C) 2008 WI...LEY-VCH Verlag GmbH and Co. KGaA, Weinheim..
