TLDR
In this article, an effective field theory of QCD and QCD-like theories beyond the Standard Model, based on the hidden local symmetry (HLS) model for the pseudoscalar mesons as Nambu-Goldstone bosons and the vector mesons (ρ) as gauge bosons, was developed.Citations

The hidden-charm pentaquark and tetraquark states
TL;DR: Recently, the LHCb Collaboration discovered two hidden-charm pentaquark states, which are also beyond the quark model as discussed by the authors, and investigated various theoretical interpretations of these candidates of the multiquark states.

Tadakatsu Sakai,Shigeki Sugimoto +1 more
TL;DR: Fujiwara et al. as mentioned in this paper investigated the interactions among the pion, vector mesons and external gauge fields in the holographic dual of massless QCD and obtained the coupling constants by performing both analytic and numerical calculations, and compare them with experimental data.

TL;DR: The current status of the Standard Model calculation of the anomalous magnetic moment of the muon is reviewed in this paper, where the authors present a detailed account of recent efforts to improve the calculation of these two contributions with either a data-driven, dispersive approach, or a first-principle, lattice approach.

Chiral symmetry breaking from five-dimensional spaces
Leandro Da Rold,Alex Pomarol +1 more
TL;DR: In this article, the breaking of the chiral symmetry in QCD using a simple five-dimensional model was studied based on the AdS/CFT correspondence and the model gave definite predictions for the spectrum of vector mesons, their decay constants and interactions as a function of one parameter related to the quark condensate.

The Renormalization group and the epsilon expansion
TL;DR: In this paper, the modern formulation of the renormalization group is explained for both critical phenomena in classical statistical mechanics and quantum field theory, and the expansion in ϵ = 4−d is explained [ d is the dimension of space (statistical mechanics) or space-time (quantum field theory)].

QCD and resonance physics. theoretical foundations
TL;DR: In this paper, a systematic study is made of the non-perturbative effects in quantum chromodynamics, where the basic object is the two-point functions of various currents and the terms of this series are shown to be of two distinct types.

Chiral perturbation theory to one loop
J. Gasser,Heinrich Leutwyler +1 more
TL;DR: In this article, the low energy representation of several Green's functions and form factors and of the na scattering amplitude are calculated in terms of a few constants, which may be identified with the coupling constants of a unique effective low energy Lagrangian.

Axial vector vertex in spinor electrodynamics
TL;DR: In this article, the axial-vector vertex in spinor electrodynamics has anomalous properties which differ with those found by the formal manipulation of field equations, and the divergence of axial vector current is not the usual expression calculated from the field equations.

Chiral Perturbation Theory: Expansions in the Mass of the Strange Quark
Jürg Gasser,Heinrich Leutwyler +1 more
TL;DR: In this paper, the authors construct the generating functional of U(3)×U(3), which allows them to calculate the Green functions up to and including terms of order p4 (at fixed radio m quark p 2 ) in terms of a few coupling constants which chiral symmetry leaves undetermined.
