title = "Search for the Λb0 →Λη ′ and Λb0 → Λη decays with the LHCb detector",
abstract = "A search is performed for the as yet unobserved baryonic Λb0 → Λη ′ and Λb0 → Λη decays with 3 fb−1 of proton-proton collision data recorded by the LHCb experiment. The B0 → Ks0η ′ decay is used as a normalisation channel. No significant signal is observed for the Λb0 → Λη ′ decay. An upper limit is found on the branching fraction of ℬΛb0→Λη′ < 3.1 × 10−6 at 90% confidence level. Evidence is seen for the presence of the Λb0 → Λη decay at the level of 3σ significance, with a branching fraction (Formula presented.).",
