Analysis of Λ0b → pK−μ+μ− decays
The differential branching fraction and angular coefficients of $$ {\Lambda}_b^0 $$→ pK−μ+μ− decays are measured in bins of the dimuon mass squared and dihadron mass. The analysis is performed using a data set corresponding to 9 fb−1 of integrated luminosity collected with the LHCb detector between...

| 520 | |a The differential branching fraction and angular coefficients of $$ {\Lambda}_b^0 $$→ pK−μ+μ− decays are measured in bins of the dimuon mass squared and dihadron mass. The analysis is performed using a data set corresponding to 9 fb−1 of integrated luminosity collected with the LHCb detector between 2011 and 2018. The data are consistent with receiving contributions from a mixture of Λ resonances with different spin-parity quantum numbers. The angular coefficients show a pattern of vector-axial vector interference that is a characteristic of the type of flavour-changing neutral-current transition relevant for these decays. | ||
