Zusammenfassung:
We extend the discussion of [1] on massive Regge excitations on the first
mass level of four-dimensional superstring theory. For the lightest massive
modes of the open string sector, universal supermultiplets common to all
four-dimensional compactifications with N = 1, 2 and N = 4 spacetime
supersymmetry are constructed respectively -- both their vertex operators and
their supersymmetry variations. Massive spinor helicity methods shed light on
the interplay between individual polarization states.
