Opposite to the supersymmetric light-cone frame separation, we show here that there is a Lorentz covariant way to identify the second class constraints such that, however, supersymmetry is broken. Consequences for the D = 10 superstring are briefly discussed.43-48engArtigo10.1016/0370-2693(94)90425-1WOS:A1994NP35100008Acesso restrito
