Abstract
"We construct the most general chirally-invariant Lagrangian for mesons in
the presence of external sources coupled to the tensor current up to the
p6-order (NLO). We provide a detailed discussion on the different
mechanisms that ensure that our final set of operators is complete and
minimal. Making use of this formalism we study two-point Green functions
including tensorcurrents and their properties in the different energy
regimes. This leads us to phenomenologic constraints in the spectrum of
J^{PC}=1^{+-} and J^{PC}=1^{--} mesons in the large-Nc limit. Finally I
will discuss a particular application for new physics search in radiative
pion decay.
