Abstract
The Mu2e experiment will search for the CLFV process of neutrinoless, coherent conversion of muon to electron in the field of an Al nucleus. One of the expected backgrounds is antiprotons produced by the proton beam at the Production Target and annihilating in the Stopping Target to produce signal-like electrons. Although not a dominant back- ground, it has a large uncertainty and cannot be suppressed by the timing cuts used to reduce the prompt background. However, at Mu2e energies, ppbar annihilation is the only source of events with multiple, simultaneous particles coming from the Stopping Target. We utilised this unique feature and developed a novel approach to reconstruct multi-track events and estimate the antiproton background.
