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 | 2,000,000 | |
| 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, pion decay disabled, weight depending on proper time, need for mixing under investigation |
| RPC internal | 1,000,000,000 | ? | number of generated POT, pion decay disabled, weight depending on proper time, need for mixing under investigation |
| RMC external | 5,000,000 | 10,000,000 | flat gamma in [85,93], negligible but comes from free from mu- --> e+ background dataset |
| RMC internal | 5,000,000 | 10,000,000 | flat gamma in [85,93], negligible but comes from free from mu- --> e+ background dataset |
| antiprotons | 100,000,000,000 | - | number of generated POT, weight with cross section*sqrt(acceptance) to optimize satistical error, 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, pion decay disabled, weight depending on proper time, need for mixing under investigation |
| RPC internal | 1,000,000,000 | ? | number of generated POT, pion decay disabled, weight depending on proper time, need for mixing under investigation |
| RMC external | 5,000,000 | 10,000,000 | flat gamma in [85,93], number of generated POT , most important after cosmics |
| RMC internal | 5,000,000 | 10,000,000 | flat gamma in [85,93], number of generated POT , most important after cosmics |
| antiprotons | 10,000,000,000 | - | number of generated POT, weight with cross section*sqrt(acceptance) to optimize satistical error, no need to do mixing |
| decays in flight and gamma conversions | ? | - | expected to be very small |
