Observation of the [lambda]0b → [lambda][phi] decay
The Λb0→Λϕ decay is observed using data corresponding to an integrated luminosity of 3.0 fb−1 recorded by the LHCb experiment. The decay proceeds at leading order via a b→ss‾s loop transition and is therefore sensitive to the possible presence of particles beyond the Standard Model. A first observat...

| 520 | |a The Λb0→Λϕ decay is observed using data corresponding to an integrated luminosity of 3.0 fb−1 recorded by the LHCb experiment. The decay proceeds at leading order via a b→ss‾s loop transition and is therefore sensitive to the possible presence of particles beyond the Standard Model. A first observation is reported with a significance of 5.9 standard deviations. The value of the branching fraction is measured to be (5.18±1.04±0.35−0.62+0.67)×10−6, where the first uncertainty is statistical, the second is systematic, and the third is related to external inputs. Triple-product asymmetries are measured to be consistent with zero. | ||
