Effective chiral Lagrangians and lattice QCD [PDF]
Nuclear 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.

On the minimality of the order p6 chiral Lagrangian
Physics Letters B, 2015 A method to find relations between the operators in the mesonic Lagrangian of Chiral Perturbation Theory at order p6 is presented. The procedure can be used to establish if the basis of operators in the Lagrangian is minimal.

Chiral perturbation theory at O(a^2) for lattice QCD
, 2003 We construct the chiral effective Lagrangian for two lattice theories: one with Wilson fermions and the other with Wilson sea fermions and Ginsparg-Wilson valence fermions.

Dynamically Generated Open and Hidden Charm Meson Systems [PDF]
, 2006 We will study open and hidden charm scalar meson resonances within two different models. The first one is a direct application of a chiral Lagrangian already used to study flavor symmetry breaking in Skyrme models. In another approach to the problem a SU(

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.

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

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 ...

New Terms for the Compact Form of Electroweak Chiral Lagrangian
, 2007 The compact form of the electroweak chiral Lagrangian is a reformulation of its original form and is expressed in terms of chiral rotated electroweak gauge fields, which is crucial for relating the information of underlying theories to the coefficients ...

Pion Breather States in QCD [PDF]
, 1998 We describe a class of pionic breather solutions (PBS) which appear in the chiral lagrangian description of low-energy QCD. These configurations are long-lived, with lifetimes greater than $10^3$ fm/c, and could arise as remnants of disoriented chiral ...
