=== CE (conversion electrons) ===
|}


=== DIO ===
* need 'single particle' and 'mixed' datasets
===Cosmics===
* a placeholder
=== RPC ===
In principle, RPC dataset could be reused for both channels
* internal conversions
* external conversions
* in-time vs out-of-time
=== RMC ===
- RMC background in mu- --> e- channel is negligible, but could be a dominant one in mu- --> e+ channel.
- for mu- --> e+, need 'single-particle' as well as 'mixed' datasets
* internal conversions
* external conversions
=== antiprotons ===
antiproton dataset can be reused for both channels , no need to generate bars with mixing
=== decays in flight===

Datasets for '2020 Mu2e sensitivity updates (in progress)

  • SU2020 stands for "'2020 Mu2e sensitivity Updates"
  • 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

mu- --> e- channel
