European Physical Journal C: Particles and Fields, 2020 We investigate the most interesting decay processes involving axions, photons and the lightest pseudoscalar mesons, making use of a chiral effective Lagrangian model with $$L=3$$ L=3 light quark flavors, which also includes the flavor-singlet ...

On QCD predictions for the chiral Lagrangian coefficients [PDF]
Journal 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 ...

Chiral Perturbation Theory at NNNLO [PDF]
, 2020 Chiral perturbation theory is a much successful effective field theory of quantum chromodynamics at low energies. The effective Lagrangian is constructed systematically order by order in powers of the momentum p2, and until now the leading order (LO ...

Anomaly matching in QCD thermal phase transition
Journal 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.

A neutrinoless double beta decay master formula from effective field theory
Journal 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
Journal 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 ...

Holography and chiral Lagrangian [PDF]
AIP 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
