dc.description.abstractThe Λ0b→Λφdecay is observed using data corresponding to an integrated luminosity of 3.0fb−1recorded by the LHCbexperiment. The decay proceeds at leading order via a b →sssloop transition and is therefore sensitive to the possible presence of particles beyond the Standard Model. A first observation is reported with a significance of 5.9standard deviations. The value of the branching fraction is measured to be (5.18 ±1.04 ±0.35+0.67−0.62) ×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.gl
