Detecting the neutral top-pion at future muon colliders

الأصل · EN

The signals of the neutral top-pion π⁰ₜ at the first muon collider (FMC) are discussed by calculating its contributions to the processes μ⁺μ⁻ bb and μ⁺μ⁻ tc. We find that the contributions to the process μ⁺μ⁻ bb are very small and the ratio of signal over square root of the background (S/√B) is smaller than 0.2. However, in most of the parameter space, the π⁰ₜ can generate 36 and up to 649 observable tc events at the FMC. The signals of the neutral top-pion π⁰ₜ may be detected via the process μ⁺μ⁻ tc at the FMC.
