Datasets for '2020 Mu2e sensitivity updates (in progress)
- SU2020 stands for "'2020 Mu2e sensitivity Updates"
- SU2020 dataset naming conventions
- Su2020 stopped particle (muon/pion/pbar) ntuples - input for physics simulations
- consider two channels - mu- --> e- and mu- --> e+
- signal windows are different, roughly speaking, [103.5-105] MeV/c and [90.5-92.5] MeV/c , so some background datasets could be the same, but some - unique for a given signal channel
