The kinematic dependences of the relative production rates, (formula presented), of Λ0b baryons and B0 mesons are measured using Λ0b → Λc+ π− and (formula presented) decays. The measurements use proton-proton collision data, corresponding to an integrated luminosity of 1 fb−1 at a centre-of-mass energy of 7 TeV, recorded in the forward region with the LHCb experiment. The relative production rates are observed to depend on the transverse momentum, pT, and pseudorapidity, η, of the beauty hadron, in the studied kinematic region 1.5 < pT < 40 GeV/c and 2 < η < 5. Using a previous LHCb measurement of (formula presented) in semileptonic decays, the branching fraction (formula presented) is obtained, where the first uncertainty is statistical, the second is systematic, the third is from the previous LHCb measurement of (formula presented) and the fourth is due to the (formula presented) branching fraction. This is the most precise measurement of a Λb0 branching fraction to date.

simulazione ASN
La simulazione può differire dall'esito di un’eventuale domanda ASN sia per errori di catalogazione e/o dati mancanti in IRIS, sia per la variabilità dei dati bibliometrici nel tempo. L’Università di Modena e Reggio Emilia non si assume alcuna responsabilità in merito all’uso che il diretto interessato o terzi faranno della simulazione.
