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	2,0000,000
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	?	?
RPC internal	?	?
RMC external	5,000,000	10,000,000	negligible in mu- --> mu- channel, could be dominant for mu- --> e+
RMC internal	5,000,000	10,000,000	negligible in mu- --> mu- channel, could be dominant for mu- --> e+
antiprotons	100,000,000,000	-	no need to do mixing
decays in flight	?	?

mu- --> e+ channel

DIO -> brem --> e+	10,000,000	10,000,000	and more
cosmics	1000		no need in mixing, rescale
