In a wide class of holographic models described by the Yang-Mills and Chern-Simons terms, we derive all the O(p6) Chiral Perturbation Theory low-energy constants. Various model-independent relations exist among the constants up to this order, generalizing the previously found relations at p4 order. Some of them can be extended to relations between different amplitudes.

    A calculation for the one-loop pion vector form-factor in Resonance Chiral Theory is provided in this talk. The amplitude is computed up to next-to-leading order in 1/NC and, by means of high-energy constraints, we are able to produce a prediction for the corresponding O(p4) Chiral Perturbation...

    In this paper we apply the chiral spinorial approach to the description of spin [FRACTION SHAPE="CASE"][NUM]3[/NUM][DEN]2[/DEN][/FRACTION] particles. Chiral components of rank 3 spinor fields are considered to be the dynamical variables of the theory. The free Lagrangian is built from the same...

    An introduction is presented in which the editors discuss various reports within the issue on topics related to gauge or string dualities including the in-medium effects in holographic models of quark-gluon plasma, the magnetic catalysis of the breaking of a chiral symmetry, and the use of...

    One-loop unitarized Chiral Perturbation Theory (UChPT) calculations, suggest a different Nc behaviour for the σ or f0(600) and ρ(770) mesons [1]: while the ρ meson becomes narrower with Nc, as is expected for a qq meson, the σ becomes broader, and its contribution to the total cross...

    We study the reaction π + N → 2π + N within the framework of heavy-baryon chiral perturbation theory of chiral order three. We find that contributions from amplitudes of chiral order three are large and play an essential role in reproducing the experimental data. In addition, we...
