Detecting the neutral top-pion at future muon colliders
Abstract
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-→t¯c. We find that the contributions to the process μ+μ-→bb¯ are very small and the ratio of the signal over the 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 t¯c events at the FMC. The signals of the neutral top-pion π0t may be detected via the process μ+μ-→t¯c at the FMC.
