Datasets-SU2020

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
RPC internal	1,000,000,000	?	number of generated POT
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, 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
