Energy levels of a muonic hydrogen atom with the use of a quark model.

The energy levels of the muonic hydrogen atom are calculated using proton charge distribution due to the nonrelativistic quark model. The charge form factor of the proton calculated in the model is in reasonable agreement with electron-scattering measurements. The effect of two orders of vacuum polarization and the finite size of the proton is included. We find good agreement with the results of earlier works, especially where the experimental charge distribution of the proton was employed. This calculation provides a useful test of nonrelativistic quark models.
