Abstract
The decay mode Λ0 b → pπ−μ+μ− is a b → d flavour changing neutral current transition and can therefore only occur at loop level in the Standard Model. In new physics models, new heavy particles can contribute and can significantly change the branching fraction of this process. The recent first observation of the decay mode Λ0 b → pπ−μ+μ− by the LHCb experiment represents the first observation of a b → d transition in the baryon sector. In these proceedings the aforementioned LHCb analysis will be outlined and the branching fraction measurement of Λ0 b → pπ−μ+μ− presented.
