A search for the X(4140) state in B +→J/ψφK + decays is performed with 0.37fb -1 of pp collisions at √s=7TeV collected by the LHCb experiment. No evidence for this state is found, in 2.4σ disagreement with a measurement by CDF. An upper limit on its production rate is set, B(B +→X(4140)K +) ×B(X(4140)→J/ψφ)/B(B +→J/ψφK +)<0.07 at 90% confidence level. © 2012 CERN.
