The decay Bs -> J/\psi K+ K- is investigated using 0.16/fb of data collected
with the LHCb detector using 7 TeV pp collisions. Although the J/\psi \phi
channel is well known, final states at higher K+K- masses have not previously
been studied. In the K+K- mass spectrum we observe a significant signal in the
f’2(1525) region as well as a non-resonant component. After subtracting the
non-resonant component, we find B(Bs->J/\psi f’_2(1525))/B(Bs->J/\psi
\phi)=(26.4 +/- 2.7 +/- 2.4)%.
