Table 1 The fit fractions of \(B^-\rightarrow D^-X_{0,1}(2900)\) in \(B^- \rightarrow D^+ D^- K^-\) and the corresponding branching fractions obtained by LHCb [1, 2]

From: Branching fractions of \(B^-\rightarrow D^-X_{0,1}(2900)\) and their implications

  Fit fraction \(Br_{\mathrm{exp}}\)
\(B^-\rightarrow D^-X_0(2900)^0\) \((5.6\pm 0.5)\%\) \((1.23\pm 0.41)\times 10^{-5}\)
\(B^-\rightarrow D^-X_1(2900)^0\) \((30.6\pm 3.2)\%\) \((6.73\pm 2.26)\times 10^{-5}\)
