Search for the X(4140) State in B+ → J/ψ ϕ K+ Decays ABSTRACT: A search for the X(4140) state in B+ → J/ψ ϕ K+ decays is performed with 0.3 fb^-1 of pp collisions at √s = 7 TeV 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+) x B(X(4140) → J/ψ ϕ)/B(B+ → J/ψ ϕ K+) < 0.07 at 90% confidence level.

Abstract

Search for the X(4140) State in B+ → J/ψ ϕ K+ Decays ABSTRACT: A search for the X(4140) state in B+ → J/ψ ϕ K+ decays is performed with 0.3 fb^-1 of pp collisions at √s = 7 TeV 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+) x B(X(4140) → J/ψ ϕ)/B(B+ → J/ψ ϕ K+) < 0.07 at 90% confidence level.
