Description
True muonium is the currently unobserved bound state of a muon and anti-muon. The potential of the LHCb experiment to make a discovery of the $1^3S_1$ state, which dominantly decays to $e^+e^-$, is discussed here. It is shown that a search for $\eta\rightarrow\gamma\mathcal{TM}$, $\mathcal{TM}\rightarrow e^+e^-$ can exceed a significance of 5 standard deviations with the expected luminosity during Run-III. Both an inclusive search for the $e^+e^-$ vertex and an exclusive search, including the photon and reconstructing the $\eta$, are possible at LHCb.
