Scientific paper

We have analyzed an integrated luminosity of 4.5 fb-1 of proton-proton collision data from the LHC with the CMS detector in search for the J/Psi J/Psi decay of the eta-b meson, the pseudo-scalar ground-state of bottomonium. The cross-section times decay width is predicted at a level of 10-4 to 10-8. We perform a maximum likelihood fit to the 4-muon invariant mass and the decay length to extract the signal yield.
