Measurement of inclusive production of charmonium states in $b$-hadron decays via their decay into $\ddot{I}•\ddot{I}•$

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1176

The inclusive production of the $\hat{I}{\cdot }_c(1S)$, $\hat{I}{\cdot }_c(2S)$ and $\ddot{I}{‡}_c$ charmonium states in $b$-hadron decays is studied with LHCb Run~2 data, corresponding to an integrated luminosit…
