Abstract
The analysis for the first observation and branching fraction measurement of the rare decay ∧\(^0\)\(_b\) → pKμ\(^+\)μ\(^-\) with respect to the control channel ∧\(^0\)\(_b\) → J/ψ pK was performed. The analysis was kept blind in ∧\(^0\)\(_b\) → pKμ\(^+\)μ\(^-\) to avoid selection bias as this decay is unobserved. The data is from proton-proton collisions recorded by the LHCb experiment in 2011 and 2012, corresponding to an integrated luminosity of 1 fb\(^-\)\(^1\) at 7 TeV and 2 fb\(^-\)\(^1\) at 8 TeV respectively. A corrected yield of (7.83 ± 0.131 ± 0.648) x 10\(^6\) ∧\(^0\)\(_b\) → J/ψ Pk candidates was measured for the full 3 fb\(^-\)\(^1\) and the analysis is currently under review by the LHCb Collaboration, awaiting approval to un-blind for the branching fraction measurement of ∧\(^0\)\(_b\) → pKμ\(^+\)μ\(^-\).
