Chromomagnetism, flavour symmetry breaking and S-wave tetraquarks
Get PDFThe chromomagnetic interaction, with full account for flavour-symmetry
breaking, is applied to S-wave configurations containing two quarks and two
antiquarks. Phenomenological implications are discussed for light, charmed,
charmed and strange, hidden-charm and double-charm mesons, and extended to
their analogues with beauty.Comment: 16 pages, 2 figures, RevTeX, Refs. updated, further typos corrected,

Isovector and hidden-beauty partners of the X(3872)
Get PDFThe isovector partners of the X(3872), recently found at BES III, Belle and
CLEO-c were predicted in a simple model based on the chromomagnetic interaction
among quarks (H. Hogaasen, J-M. Richard and P. Sorba, Phys. Rev. D73, 054013,
2006). The extension to the hidden-beauty sector is discussed.Comment: Some references added. More details on the width and decay modes. To
appear in Phys. Lett.
