Abstract
In this paper, we investigate the production of a true muonium state, which is an atom consisting of a ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ bound state, by $\ensuremath{\gamma}\ensuremath{\gamma}$ interactions in ultraperipheral PbPb collisions, considering an accurate treatment of the absorptive corrections and for the nuclear form factor. The rapidity distributions and cross sections are estimated considering the Relativistic Heavy Ion Collider, Large Hadron Collider, and Future Circular Collider energies. Our results indicate that the experimental analysis can be useful to observe the true muonium state.
Highlights
In recent years, the STAR [1], ALICE [2], ATLAS [3], and CMS [4] Collaborations have release data for the dilepton production by γ γ interactions in heavy ion collisions at different center-of-mass energies and distinct centralities
For a true muonium in the ground state, a para-TM state decays into an even number of photons, while the ortho-TM state must decay into an odd number
We focus on the production of para-TM states in ultraperipheral PbPb collisions
