Abstract

In this paper, chiral Lagrangians with vector mesons are constructed across multiple representations, including those at next-to-leading order in the vector-field representation, as well as at next-to-next-to-leading order in the tensor-field and hidden local symmetry representations. At next-to-leading order, redundant terms in the other literature are also identified in the both tensorfield and hidden local symmetry representations. Relations are established between the next-tonext-to-leading order low-energy constants of the pseudoscalar mesonic Lagrangians and those in the hidden local symmetry representation at tree level. Additionally, the equivalence between the tensor-field and hidden local symmetry representations is examined.
