Production rates of ds+ds- and dd¯ molecules in b decays

HIGHLIGHTS

• who: Jia-Ming Xie and colleagues from the SchoolBeihang University, Beijing, China have published the Article: Production rates of Ds+Ds- and DDu00af molecules in B decays, in the Journal: (JOURNAL) of 11/08/2022
• what: The authors assume that there exist two molecules near the - DDu0304 and D- s Ds mass thresholds, denoted as X qqu0304 and X ssu0304, and employ the effective Lagrangian approach to investigate their production rates in B decays via the triangle mechanism. In terms of the branching ratios of 0 and B- u2192 D - Du03040 the authors determine a . . .
