N2 - Branching fraction and effective lifetime measurements of the rare decay Formula Presented and searches for the decays Formula Presented and Formula Presented are reported using proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV, corresponding to a luminosity of Formula Presented. The branching fraction Formula Presented and the effective lifetime Formula Presented are measured, where the first uncertainty is statistical and the second systematic. No significant signal for Formula Presented and Formula Presented decays is found and upper limits Formula Presented and Formula Presented at the 95% C.L. are determined, where the latter is limited to the range Formula Presented. The results are in agreement with the standard model expectations.
