Abstract
Massless super quantum electrodynamics (SQED) and massless U(N) SQCD are examined in the somewhat improved Born-Oppenheimer approximation. The leading asymptotic behaviors of the wave functionals are fully respected. Supersymmetry is shown to be unbroken in both cases. CP or R symmetry is spontaneously broken. The Witten index in these theories is well defined despite the abnormal degeneracy, and the values agree with their massive counterparts. Clarification in connection with other approaches is made.
