Search for the $X(4140)$ state in $B^+\to J/\psi\phi K^+$ decays

A search for the $X(4140)$ state in $B^+\to J/\psi\phi K^+$ decays is performed with 0.37 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=7$ TeV collected by the LHCb experiment. No evidence for this state is found, in $2.4\,\sigma$ disagreement with a measurement by CDF. An upper limit on its production...
