“…The PDF of f (E µ − e + − x), where f (x) is the standard Landau distribution, was used to fit the signal positron distribution. The fitted PDF was normalized to N µ − e + , which is determined by the value of Br(µ − −e + ), while N µ − stop of 10 18 and E of 10 −2 were chosen to achieve the µ − − e − conversion sensitivity of O(10 −16 ) with the aluminum target, based on the specifications of the upcoming experiments [30][31][32].…”

“…(2) In principle, the experimental sensitivity of the µ − −e + conversion can significantly increase with the future µ − − e − conversion experiments because the event signatures (e ± ) of both physics processes can be easily distinguished by the charge identification. However, in the upcoming COMET and Mu2e experiments 1 [30][31][32], which were originally designed to search for the µ − − e − conversion with the sensitivity of O(10 −16 ), a similar scale of the sensitivity for the µ − −e + conversion can only be achievable in the case of employing a proper material for a muon-stopping target nucleus. This limitation of µ − − e + conversion sensitivity is due to the backgrounds from radiative muon capture (RMC).…”

Future experimental improvement for the search of lepton-number-violating processes in the eμ sector

The conservation of lepton flavor and total lepton number are no longer guaranteed in the Standard Model after the discovery of neutrino oscillations. µ − + N (A, Z) → e + + N (A, Z − 2) conversion in a muonic atom is one of the most promising channels to investigate the lepton number violation processes, and measurement of the µ − − e + conversion is planned in future µ − − e − conversion experiments with a muonic atom in a muon-stopping target. This letter discusses experimental strategies to maximize the sensitivity of the µ − − e + conversion experiment by introducing the new requirement of the mass relation of M (A, Z − 2) < M (A, Z − 1), where M (A, Z) is the mass of the muon-stopping target nucleus, to eliminate the backgrounds from radiative muon capture. The sensitivity of the µ − − e + conversion is expected to be improved by four orders of magnitude in forthcoming experiments using a proper target nucleus that satisfies the mass relation. The most promising isotopes found are 40 Ca and 32 S.
