Description
The theta term is an allowable CP violating term in the QCD Lagrangian connected to topology; the coefficient multiplying it is zero to very high accuracy. Despite being very small they way QCD varys with theta allows one to probe aspects of the QCD vacuum including the interplay of chiral physics and topology. This talk discusses the issue with an emphasis on possible scenarios in which the theta dependence could be quite different from what is commonly assumed.
