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

Taispeáin leaganacha eile (1)

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 sec...
