摘要：

We analize the most general low-energy effective Lagrangian including local parity violating terms parametrized by an axial chemical potential mu(5). This result is obtained following the external source method, up to O(p(4)) order in the chiral expansion for two light flavours. We show that the O(p(4)) Lagrangian includes new terms proportional to mu(2)(5) and new low-energy constants. Finally, the mu(5) and temperature dependences of several observables related to the vacuum energy density are studied.
