The prospects of an angular analysis of the Lambda(0)(b) -> Lambda(1520) l(+) l(-) decay are presented, with sensitivity studies to determine the experimental precision on angular observables related to lepton distribution and their potential to identify New Physics. The forward-backward lepton asymmetry at low dilepton invariant mass is particularly promising, and NP scenarios can be distinguished from the SM case with the data collected between Run 3 and Upgrade 2 of the LHCb experiment.
We present the prospects of an angular analysis of the Lambda(0)(b) -> Lambda(1520) l(+) l(-) decay. Using the expected yield in the current dataset collected at the LHCb experiment, as well as the foreseen ones after the LHCb upgrades, sensitivity studies are presented to determine the experimental precision on angular observables related to the lepton distribution and their potential to identify New Physics. The forward-backward lepton asymmetry at low dilepton invariant mass is particularly promising. NP scenarios favoured by the current anomalies in b -> sl(+) l(-) decays can be distinguished from the SM case with the data collected between the Run 3 and the Upgrade 2 of the LHCb experiment.
