Search for $X(4140)$ in $B^+\to J/\psi\phi K^+$
We search for the narrow $X(4140)\to J/\psi\phi$ state reported by CDF in $B^+\to J/\psi\phi K^+$ decays. Using a sample of 376 pb$^{-1}$ of pp collision data collected by the LHCb experiment we find no evidence for this state in $B^+\to J/\psi\phi K^+$ decays and set upper limits on its production...
