Search for rare b to open-charm two-body decays of baryons at LHCb

Universität Rostock, 2020

Abstract: A search for the rare two-body decays Λb → D°Λ and Ξb° → D°Λ is performed with proton-proton collision data, collected by the LHCb experiment at a center-of-mass energy of 13 TeV. The decay Λb → D°Λ is seen with a statistical significance of 5.5 standard deviations and constitutes the discovery for this decay. An excess of Ξb° → D°Λ candidates w.r.t. the background is observed with a statistical significance of 1.8 standard deviations.
