Abstract
A search for a long-lived scalar particle χ is performed, looking for the decay B[superscript +]→K[superscript +]χ with χ→μ[superscript +]μ[superscript -] in pp collision data corresponding to an integrated luminosity of 3 fb[superscript -1], collected by the LHCb experiment at center-of-mass energies of √s =7 and 8 TeV. This new scalar particle, predicted by hidden sector models, is assumed to have a narrow width. The signal would manifest itself as an excess in the dimuon invariant mass distribution over the Standard Model background. No significant excess is observed in the accessible ranges of mass 250
