Descriptions
We study relativistic bound states of two kinds of the massive Dirac particles with a current-current interaction in 2-dimensional space-time. We have two types of the solutions; normal and abnormal solutions. The former solution shows that the binding energy of the particle-particle pair from the positron theory is smaller than that from the single electron theory.
