  We approach the issue of the discovery of new physics at high energies
associated with the proposed International Linear Collider in the presence of
longitudinal as well as transverse electron and positron beam polarization. We
determine the beam polarization dependence and the angular distribution of a
particle of arbitrary spin in a one-particle inclusive final state produced in
e+ e- collisions through the interference of gamma or Z amplitude with the
amplitude from new interactions having arbitrary space-time structure. We thus
extend the results of Dass and Ross proposed at the time of the discovery of
neutral currents, to beyond the standard model currents. We also extend the
case of e+ e- annihilation in the s-channel to the production of bosons due to
t- and u-channel processes. Our work provides an approach to model-independent
determination of the space-time structure of beyond the standard model
interactions. We briefly discuss applications of the framework to popular
extensions of the standard model, and demonstrate that our framework is general
enough to account for certain results in the minimal supersymmetric standard
model.
