The order p8 mesonic chiral Lagrangian

A bstractWe derive the chiral Lagrangian at next-to-next-to-next-to-leading order (NNNLO) for a general number Nf of light quark flavours as well as for Nf = 2, 3. We enumerate the contact terms

Chiral Lagrangian and chiral quark model from confinement in QCD

The effective chiral Lagrangian in both nonlocal form LECCL and standard local form LECL, derived in the vacuum correlator formalism in QCD, is studied in the chiral perturbation theory. It is shown,

Chiral Perturbation Theory at NNNLO

The construction of the Lagrangian is considered and the pion mass and decay constant at the same order are discussed, which are fundamental quantities to study for chiral perturbation theory.

On the mesonic Lagrangian of order p^6 in chiral SU(2)

We show that the number of operators in the presently known mesonic chiral Lagrangian of order p^6 in the two-flavour sector can be reduced by at least one from 57 to 56 by providing an explicit

Extension of the chiral perturbation theory meson Lagrangian to order p6.

The claim to have obtained the most general Lagrangian relies on this systematic construction and on the elimination of redundant quantities using relations of which the author is aware, rather than on a general formal proof of either completeness or independence.

Holography, chiral Lagrangian and form factor relations

A bstractWe derive all the $ \mathcal{O}\left( {{p^6}} \right) $ Chiral Perturbation Theory low-energy constants from a class of gravity dual models of QCD described by the Yang-Mills and
