Detecting the neutral top-pion at future muon colliders

Abstract

The signals of the neutral top-pion ${\pi }_t^0$ at the first muon collider (FMC) are discussed by calculating its contributions to the processes ${\mu }^{+}{\mu }^{-}⟶b\bar{b}$ and ${\mu }^{+}{\mu }^{-}⟶\bar{t}c$. We find that the contributions to the process ${\mu }^{+}{\mu }^{-}⟶b\bar{b}$ are very small and the ratio of signal over square root of the background ($S/\sqrt{B})$ is smaller than 0.2. However, in most of the parameter space, the ${\pi }_t^0$ can generate 36 and up to 649 observable $\bar{t}c$ events at the FMC. The signals of the neutral top-pion ${\pi }_t^0$ may be detected via the process ${\mu }^{+}{\mu }^{-}⟶\bar{t}c$ at the FMC.
