Chiral Lagrangians [PDF]

International Journal of Modern Physics A, 2001
An overview of the field of Chiral Lagrangians is given. This includes Chiral Perturbation Theory and resummations to extend it to higher energies, applications to the muon anomalous magnetic moment, $\epsilon^\prime/\epsilon$ and others.Comment: Invited

The order $p^8$ mesonic chiral Lagrangian [PDF]

Journal of High Energy Physics, 2019
We derive the chiral Lagrangian at next-to-next-to-next-to-leading order (NNNLO) for a general number $N_f$ of light quark flavours as well as for $N_f=2,3$. We enumerate the contact terms separately.

Chiral Lagrangians with tensor sources [PDF]

AIP Conference Proceedings, 2007
The implementation of tensor sources in Chiral Lagrangians allows the computation of Green functions and form factors involving tensor currents, that is, quark bilinears of the form \bar{q}_i\sigma^{\mu\nu}q_j.

Quark models and chiral lagrangians

Nuclear Physics B, 1990
Abstract We consider the description of low-energy hadronic physics in terms of quark models, and explore its connection with chiral lagrangians. The chiral lagrangians with four derivatives arising from the interactions of the Goldstone bosons with quarks are calculated.

Species Doubling and Chiral Lagrangians [PDF]

Physical Review Letters, 1996
Coupling gauge fields to the chiral currents from an effective Lagrangian for pseudoscalar mesons naturally gives rise to a species doubling phenomenon similar to that seen with fermionic fields in lattice gauge theory.

Relations for low-energy constants in baryon chiral perturbation theory with explicit $$\Delta (1232)$$ Δ ( 1232 ) derived from the chiral quark model

European Physical Journal C: Particles and Fields, 2023
We study the relations between low-energy constants in the chiral Lagrangians with $$\Delta (1232)$$ Δ ( 1232 ) and those in the quark-level description model up to the third chiral order.

T-dual superstring Lagrangian with double zweibeins

Journal of High Energy Physics, 2020
We present superstring Lagrangians with manifest T-duality. The Lagrangian version of the section conditions are necessary to make Lagrangians to be general coordinate invariant. We show the general solution of section conditions.
