The paper predicts effective true muonium production cross sections of 1.23 μb in 200 GeV AuAu and 14.2 μb in 5.02 TeV PbPb collisions, corresponding to O(10^4) and O(10^5) atoms per billion central events.

abstract
Results are obtained for the decay rate of ortho and para states and for the hyperfine structure of the dimuonic system mu+ mu- (dimuonium). We calculate next--to-leading order radiative corrections. It is shown that previously reported results for the decay rate of ortho states are incomplete. The decay rate is strongly influenced by the electronic vacuum polarization in the far time-like asymptotic region and thus allows for a test of QED in a previously unexplored kinematic regime.
