Description
A light-front quantization study of the nonperturbative
spectrum of the bound state $(\mu^+\mu^-)$, true muonium, has been
performed. Using Pad\'{e} approximants, it has been possible to
extract continuum and infinite-cutoff limits for the singlet and
triplet states for a range of coupling constants $\alpha$. This allows for an investigation of the $\alpha$ dependence of the light-front spectra, the results of which are compared to standard calculations. Decay constants have also been
obtained. Improved calculations have been undertaken for the energy
shifts due to the presence of a second, lighter flavor ($e$).
Finally, initial results for three-flavor ($e$, $\mu$, $\tau$)
calculations are presented.
