Low energy phenomenological chiral Lagrangians

, 1987
We develop a phenomenological Lagrangian that satisfies the requirements of the so called alternative schemes designed to model low energy meson phenomenology.

Theta angle in holographic QCD

EPJ Web of Conferences, 2017
V-QCD is a class of effective holographic models for QCD which fully includes the backreaction of quarks to gluon dynamics. The physics of the θ-angle and the axial anomaly can be consistently included in these models.

KAON DECAYS AND A DETERMINATION OF THE SCALE OF CHIRAL SYMMETRY

, 1984
Published version is located at http://prd.aps.org/abstract/PRD/v30/i3/p587_1Using effective chiral Lagrangians, we consider the occurrence of quadratic terms in the ΔI=1/2 K→3π matrix element.

S-Wave Meson-Nucleon Interactions and the Meson Mass in Nuclear Matter From Chiral Effective Lagrangians

, 1995
Chiral effective lagrangians may differ in their prediction of meson-nucleon scattering amplitudes off-meson-mass-shell, but must yield identical S-matrix elements.

The Mesonic Chiral Lagrangian of Order

, 2007
: We construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic even-intrinsic-parity sector at order p 6 . The Lagrangian contains 112 in principle measurable + 3 contact terms for the general case of n light flavours, 90 ...

Hadronic interactions from effective chiral Lagrangians of quarks and gluons

, 1997
Effective chiral Lagrangians involving constituent quarks, Goldstone bosons and long-distance gluons are believed to describe the strong interactions in an intermediate energy region between the confinement scale and the chiral symmetry breaking scale ...

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

, 2023
We study the relations between low-energy constants (LECs) in the chiral Lagrangians with $\Delta(1232)$ and those in the quark-level description model up to the third chiral order.
