  We study the production of the dimuonium (also known as true muonium) in two
and three photon fusion processes in nucleus--nucleus collisions at the CERN
Large Hadron Collider (LHC) energies. A new formalism is introduced for the
production process and valuable new information is extracted which will be
helpful in proposals of future experiments. We explore the phase space
constraints, the reaction mechanisms, and how the dimounium decay observables
might be jeopardized by other physical processes. We show that the energies
available at the large hadron collider at CERN might lead to the first
identification of the dimounium in a terrestrial laboratory.
