On QCD predictions for the chiral Lagrangian coefficients [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2002
Based on a previous study of deriving the chiral Lagrangian (CL) from QCD, we illustrate the main feature of QCD predictions for the CL coefficients (CLC) in certain approximations. We first show that, in the large-N(c) limit, the anomaly part contributions to the CLC are exactly cancelled by certain terms in the normal part contributions (NPC), so ...

The Lagrangian method for chiral symmetry [PDF]

open access: yes, 1969
We describe the non linear realizations of chiral symmetry group and study some of its implications in elementary particle phycics. In Chapter 1, the basic concepts of non linear realization techniques are introduced the way of reviewing the special case

Reinterpretation of Effective Chiral Lagrangian

open access: yes, 2000
10 pages, 1 figureEffective tree Chiral Lagrangian is interpreted as a power series expansion of the kinematical variables. In the presence of the strong interaction this expansion is valid below the unitarity cut, hence in the unphysical region ...

Effective chiral Lagrangians and lattice QCD [PDF]

open access: yesNuclear Physics B, 2000
We propose a general method to obtain accurate estimates for some of the "low-energy constants" in the one-loop effective chiral Lagrangian by means of simulating lattice QCD. In particular, the method is sensitive to those constants whose values are required to test the hypothesis of a massless up-quark.

Anomaly matching in QCD thermal phase transition

open access: yesJournal of High Energy Physics, 2019
We study an ’t Hooft anomaly of massless QCD at finite temperature. With the imaginary baryon chemical potential at the Roberge-Weiss point, there is a ℤ2 symmetry which can be used to define confinement.

Holography and chiral Lagrangian [PDF]

open access: yesAIP Conference Proceedings, 2012
In a wide class of holographic models described by the Yang-Mills and Chern-Simons terms, we derive all the ${\cal O}(p^6)$ Chiral Perturbation Theory low-energy constants. Various model-independent relations exist among the constants up to this order, generalizing the previously found relations at $p^4$ order. Some of them can be extended to relations

New synthetic uses for chiral 1,3-dioxolan-4-ones [PDF]

open access: yes, 2008
The behaviour of chiral 1,3-dioxolan-4-ones, derived from reaction of mandelic and lactic acid with pivalaldehyde, as chiral acyl anion equivalents has been examined.

A neutrinoless double beta decay master formula from effective field theory

open access: yesJournal of High Energy Physics, 2018
We present a master formula describing the neutrinoless-double-beta decay (0νββ) rate induced by lepton-number-violating (LNV) operators up to dimension nine in the Standard Model Effective Field Theory.

Chiral perturbation theory for nonzero chiral imbalance

open access: yesJournal of High Energy Physics, 2020
We construct the most general low-energy effective lagrangian including local parity violating terms parametrized by an axial chemical potential or chiral imbalance μ 5, up to O p 4 $$ \mathcal{O}\left({p}^4\right) $$ order in the chiral expansion for ...
