| 英文摘要 | The ratio of branching fractions r-k/pi = b (b-c(+) -> j/psi k+)/b(b-c(+) -> j/psi pi(+)) is measured with pp collision data collected by the lhcb experiment at centre-of-mass energies of 7tev and 8tev, corresponding to an integrated luminosity of 3 fb(-1). it is found to be r-k/pi = 0.079 +/- 0.007 +/- 0.003, where the first uncertainty is statistical and the second is systematic. this measurement is consistent with the previous lhcb result, while the uncertainties are significantly reduced. |
