Search for long-lived scalar particles in B+→K+χ(μ+μ−) decays

Abstract:

A search for a long-lived scalar particle χ is performed, looking for the decay B+→K+χ with χ→μ+μ- in pp collision data corresponding to an integrated luminosity of 3 fb-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 o...
