| 英文摘要 | The decay b+ -> psi(2s) phi(1020) k+ is observed for the first time using data collected from pp collisions at root s = 8 tev by the cms experiment at the lhc, corresponding to an integrated luminosity of 19.6 fb(-1). the branching fraction of this decay is measured, using the mode b+ -> psi(2s) k+ as normalization, to be (4.0 +/- 0.4 (stat)+/- 0.6 (syst)+/- 0.2 (b)) x 10(-6), where the third uncertainty is from the measured branching fraction of the normalization channel.
