Scalar-scalar ladder model in the unequal-mass case. III - Numerical studies of the p-wave case

The eigenvalue problem for the p-wave bound states formed with two unequal- mass scalar particles through massive scalar particle exchange is analyzed numerically in the framework of the Bethe-Salpeter ladder model. As in the s-wave case, the eigenvalues of the coupling constant are found to become c omplex for some mass configurations in some range of the bound state mass. The Bethe-Salpeter amplitudes of the low-lying bound states are also invest igated.
