A QCD sum rule calculation of the X±(5568)→Bs0π± decay width
To understand the nature of the X(5568), recently observed in the mass spectrum of the Bs0π± system by the D0 Collaboration, we have investigated, in a previous work, a scalar tetraquark (diquak–antidiquark) structure for it, within the two-point QCD sum rules method. We found that it is possible to...
