than two doublets. Finally, recent attempts at constructing models with low-energy supersymmetry arc reviewed, and it is shown that in many models, fairly stringent tree-level mass relations among the Higgs scalars can be found. These relations are interesting in that they do not refer to the supersymmetric partners of ordrnary particles. and they are most restrictive in models in which the supersymmetry is explicitly broken, i.e., via arbitrary mass terms.

LowEnergy
Low-energy quantities like the scattering length and effective range parameter are directly derived from the threshold behavior of the scattering amplitude for Schrodinger Hamiltonians with short-range and Coulomb-type interactions. The possibility of zero-energy resonances and zero-energy bound states of the underlying Hamiltonian is explicitly taken into account. No spherical symmetry of the interaction is assumed.

Various symmetries of inelastic proton-nucleus scattering within the Glauber model are discussed. They are obtamed from symmetries of the corresponding proton-nucleon amplitude. In particular. it is shown that the polarization and analyzing power are in general not equal.
