Two particles Dirac type equation question

Click For Summary
SUMMARY

The discussion centers on the two-body Dirac equations (2BDE) and the role of confining potentials in relativistic constituent quark models. Participants clarify that the potential is an input to the problem, not a solution, and that various forms of confining potentials are assumed to analyze the system's possible states. The referenced paper discusses different formulations of 2BDE and their applications in particle physics.

It seems that the potential between the particles can be assumed of different forms, shouldn't the potential be a solution of the problem.
Thanks

No, it's an input to the problem. You assume a particular potential, then solve the equations to see what the possible states of the system are.

Thanks for the reply.

from the introduction
"In recent years the two body Dirac equations (2BDE) in different formulations with various confining potentials are used as a relativistic constituent quark models"
From where/what these confining potentials are generated.
