Abstract The conditions are discussed under which in functional quantum theory of the nonlinear spinorfield with indefinite metric the probabilistic interpretation can be restored. This leads to a close connection of confinement, composite particles and the new subquark models of matter.

Field Theoretical Model

A special field theoretical model is constructed to study the problem of probability interpretation of a quantum theory with indefinite metric. The model is based on the HEISENBERG dipole-ghost version of the LEE model, but with an additional V Θ-interaction. This interaction yields bound states in the sector N+2 Θ. One gets a situation similar to a case studied by PAULI and KÄLLÉN. It seems that the arising difficulty can be solved only by means of a boundary condition suggested by BOGOLIUBOV. However, such a condition excludes the possibility of interpreting our bound states as “physically realizable” states.
