Query: The Theory of Parity Violation in Few-Nucleon Systems   We review recent progress in the theoretical description of hadronic parity
violation in few-nucleon systems. After introducing the different methods that
have been used to study parity-violating observables we discuss the available
calculations for reactions with up to five nucleons. Particular emphasis is put
on effective field theory calculations where they exist, but earlier and
complementary approaches are also presented. We hope this review will serve as
a guide for those who wish to know what calculations are available and what
further calculations need to be completed before we can claim to have a
comprehensive picture of parity violation in few nucleon systems.
