Exploring X(5568) as a meson molecule
(Springer Verlag, 2016-10)
The parameters, i.e. the mass and current coupling of the exotic X(5568) state observed by the D0 Collaboration as well as the decay width of the process X→B0sπ+X→Bs0π+ , are explored using the BK¯¯¯¯¯BK¯ molecule ...
Width of the exotic Xb (5568) state through its strong decay to Bs0 π+
(American Physical Society, 2016-06)
The width of the newly observed exotic state Xb(5568) is calculated via its dominant strong decay to Bs0π+ using the QCD sum rule method on the light cone in conjunction with the soft-meson approximation. To this end, the ...
