Observation of the Y (4140) structure in the J/ψϕ mass spectrum in B±→ J/ψϕK± decays

Observation of the Y (4140) structure in the J/ψϕ mass spectrum in B±→ J/ψϕK± decays

© 2017 World Scientific Publishing Company. The observation of the Y (4140) structure in B± → J/ΨφK± decays produced in pp collisions at √ s = 1.96 TeV is reported with a statistical significance greater than 5 standard deviations. A fit to the J/Ψφ mass spectrum is performed assuming the presence o...
