Abstract: (APS)

We investigate the decay

B^{+} \to J / ψ ϕ K^{+}

in a search for the

X (4140)

state, a narrow threshold resonance in the

J / ψ ϕ

system. The data sample corresponds to an integrated luminosity of

10.4 {fb}^{- 1}

of

p \bar{p}

collisions at

\sqrt{s} = 1.96 TeV

collected by the D0 experiment at the Fermilab Tevatron collider. We observe a mass peak with a statistical significance of 3.1 standard deviations and measure its invariant mass to be

M = 4159.0 \pm 4.3 (stat) \pm 6.6 (syst) MeV

and its width to be

Γ = 19.9 \pm 12.6 {(stat)}_{- 8.0}^{+ 3.0} (syst) MeV

.
