摘要：

The OSp(2\2)-invariant planar dynamics of a D = 4 superparticle near the horizon of a large mass extreme black hole is described by an N = 2 superconformal mechanics, with the SO(2) charge being the superparticle's angular momentum. The non-manifest superconformal invariance of the superpotential term is shown to lead to a shift in the SO(2) charge by the value of its coefficient, which we identify as the orbital angular momentum. The full SU(1,1\2) invariant dynamics is found from an extension to N = 4 superconformal mechanics. [S0556-2821(99)01608-2].
