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

Dataset N(generated events) signal-only N(events) mixed comments
CE (mu-Al --> e-Al) 1,000,000 2,0000,000
DIO 1,000,000 2,000,000
cosmics ? - about 40 Mu2e livetimes generated with CRY, rescale flux with Corsika, no need to do mixing
RPC external 1,000,000,000 ? number of generated POT
RPC internal 1,000,000,000 ? number of generated POT
RMC external 5,000,000 10,000,000 number of generated POT, negligible but comes from free from mu- --> e+ background dataset
RMC internal 5,000,000 10,000,000 number of generated POT, negligible but comes from free from mu- --> e+ background dataset
antiprotons 100,000,000,000 - number of generated POT, no need to do mixing
decays in flight and gamma conversions ? ? negligible in CD3

mu- --> e+ channel

Dataset N(generated events) signal-only N(events) mixed comments
CE (mu-Al --> e+Al) 1,000,000 2,0000,000
DIO -> brem --> e+ 1,000,000 2,000,000
cosmics ? - ~40 Mu2e livetimes generated with CRY, rescale flux with Corsika, no need to do mixing
RPC external 1,000,000,000 ? number of generated POT
RPC internal 1,000,000,000 ? number of generated POT
RMC external 5,000,000 10,000,000 number of generated POT , most important after cosmics
RMC internal 5,000,000 10,000,000 number of generated POT , most important after cosmics
antiprotons 10,000,000,000 - number of generated POT , no need to do mixing
decays in flight and gamma conversions ? - expected to be very small
