Abstract |
Decays of Xi(-)(b) and Omega(-)(b) baryons to Lambda(+)(c)h(-)h(-) final states, with h(-)h '(-) being pi(-)pi(-), K-pi(-) and K-K- meson pairs, are searched for using data collected with the LHCb detector. The data sample studied corresponds to an integrated luminosity of 8.7 fb(-1) of pp collisions collected at centre-of-mass energies root s = 7, 8 and 13 TeV. The products of the relative branching fractions and fragmentation fractions for each signal mode, relative to the B- -> Lambda(+)(c)(p) over bar pi(-) mode, are measured, with Xi(-)(b) -> Lambda K-+(c)-pi(-), Xi(-)(b) -> Lambda+cK-K- and Omega(-)(b) -> Lambda+cK-K- decays being observed at over 5 sigma significance. The Xi(-)(b) -> Lambda K-+(c)-pi(-) mode is also used to measure the Xi(-)(b) production asymmetry, which is found to be consistent with zero. In addition, the B- -> Lambda(+)(c)(p) over barK(-) decay is observed for the first time, and its branching fraction is measured relative to that of the B- -> Lambda(+)(c)(p) over bar pi(-) mode. |
