Description:

Effective field theory Wilson coefficients can be bounded by applying
basic principles including unitarity, crossing and high energy-growth
of amplitudes in the underlying theory.  We present evidence that much
stronger bounds should exist for physically sensible theories that
remain to be fully uncovered.  We do this in the context of the
four-graviton amplitude which is believed to obey strict constraints
in the high-energy Regge limit.  We also describe nontrivial
constraints on corrections to the graviton three-point coupling and on
inelastic graviton processes.
