| 英文摘要 | The ratios of the branching fractions of the decays do lambda(+)(c) -> , p pi(-)pi(+), lambda(+->)(c) pk(-)k(+), and lambda(+)(c) -> p pi k--(+) with respect to the cabibbo-favoured lambda(+)(c) -> pk(-)pi(+) decay are measured using proton-proton collision data collected with the lhcb experiment at a 7 tev centre-of-mass energy and corresponding to an integrated luminosity of 1.0 fb(-1): b(lambda(+)(c) -> p pi(-)pi(+))/b(lambda(+)(c) -> pk(-)pi(+)) = (7.44 +/- 0.08 +/- 0.18)%. b(lambda(+)(c) -> pk(-)k(+))/b(lambda(+)(c) -> pk(-)pi(+) = (1.70 +/- 0.03 +/- 0.03)%, b(lambda(+)(c) -> p pi(-)pi k-+(+))/b(lambda(+)(c) -> pk(-)pi(+) = (0.165 +/- 0.015 +/- 0.005)%, where the uncertainties are statistical and systematic, respectively. these results are the most precise measurements of these quantities to date. when multiplied by the world average value for b(lambda(+)(c) -> p pi(-)pi(+)), the corresponding branching fractions are b(lambda(+)(c) -> p pi(-)pi(+) = (4.72 +/- 0.05 +/- 0.11 +/- 0.25) x 10(-3), b(lambda(+)(c) -> pk(-)k(+)) = (1.08 +/- 0.02 +/- 0.02 +/- 0.06) x 10(-3), b(lambda(+)(c) -> , p pi k--(+)) = (1.04 +/- 0.09 +/- 0.03 +/- 0.05) x 10(-4), where the final uncertainty is due to b(lambda(+)(c) -> pk(-)pi(+)). |
