Abstract: (arXiv)

We investigate the decay

B_s^0 \rightarrow J/\psi K^+ K^-

for invariant masses of the

K^+K^-

pair in the range

1.35<M(K^+K^-)<2

GeV. The data sample corresponds to an integrated luminosity of 10.4 fb

^{-1}

of

p \bar{p}

collisions at

\sqrt{s} = 1.96

TeV accumulated with the D0 detector at the Fermilab Tevatron collider. From the study of the invariant mass and spin of the

K^+K^-

system, we find evidence for the two-body decay \bsf and measure the relative branching fraction of the decays \bsf and \bsdec to be

R_{f_2^{\prime}/\phi} = 0.19 \pm 0.05 \rm \thinspace{(stat)} \pm 0.04 \rm \thinspace{(syst)}

.
