Branching fraction measurement of the decay 𝐵+ →𝜓(2𝑆)𝜙(1020)𝐾+
The branching fraction of the decay 𝐵+ →𝜓(2𝑆)𝜙(1020)𝐾+, relative to the topologically similar decay 𝐵+ →𝐽/𝜓𝜙(1020)𝐾+, is measured using proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of 9...

| 520 | |a The branching fraction of the decay + →(2)(1020)+, relative to the topologically similar decay + →/(1020)+, is measured using proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of 9 fb−1. The ratio is found to be 0.061 ±0.004 ±0.009, where the first uncertainty is statistical and the second systematic. Using the world-average branching fraction for + →/(1020)+, the branching fraction for the decay + →(2)(1020)+ is found to be (3.0 ±0.2 ±0.5 ±0.2) ×10−6, where the first uncertainty is statistical, the second systematic, and the third is due to the branching fraction of the normalization channel. | ||
