Currents, charges, and canonical structure of pseudodual chiral models

We discuss the pseudodual chiral model to illustrate a class of two-dimensional theories which have an innite number of conservation laws but allow particle production, at variance with naive expectations. We describe the symmetries of the pseudodual model, both local and nonlocal, as transmutations of the symmetries of the usual chiral model. We rene the conventional algorithm to more eciently produce the nonlocal symmetries of the model, and we discuss the complete local current algebra for
more » ... rrent algebra for the pseudodual theory. W e also exhibit the canonical transformation which connects the usual chiral model to its fully equivalent dual, further distinguishing the pseudodual theory.
