| dc.description.abstract | The decay ¯¯¯B0s→J/ψK+K− is investigated using 0.16 fb−1 of data collected with the LHCb detector using 7 TeV pp collisions. Although the J/ψϕ channel is well known, final states at higher K+K− masses have not previously been studied. In the K+K− mass spectrum we observe a significant signal in the f′2(1525) region as well as a nonresonant component. After subtracting the nonresonant component, we find B(¯¯¯B0s→J/ψf′2(1525))/B(¯¯¯B0s→J/ψϕ)=(26.4±2.7±2.4)%. | eng |
