The anomalous chiral Lagrangian at order p8

Journal of High Energy Physics
Abstract We derive the order p 8 Lagrangian of odd intrinsic parity for mesonic chiral perturbation theory, and provide the resulting operator basis in the supplementary material. Neglecting the non-zero singlet trace, we find 999 operators for a general number of quark flavours N f

Chiral lagrangians and WW scattering

Nuclear Physics B, 1991
Recently, it has been proposed that the scattering of strongly interacting longitudinal gauge bosons can be studied using chiral perturbation theory. By fitting the energy dependence of the scattering amplitudes in the energy region 0.5 TeV < √s < 1.2 TeV one is sensitive to the nature of electroweak symmetry breaking.

Electroweak chiral Lagrangians and the Higgs properties at the one-loop level

EPJ Web of Conferences, 2014
In these proceedings we explore the use of (non-linear) electroweak chiral Lagrangians for the description of possible beyond the Standard Model (BSM) strong dynamics in the electroweak (EW) sector.

Isospin breaking and f0(980)-a0(980) mixing in the η(1405) → π0f0(980) reaction

EPJ Web of Conferences, 2014
We make a theoretical study of the η(1405) → π0f0(980) and η(1405) → π0a0(980) reactions to determine the isospin violation and the mixing of the f0(980) and a0(980) resonances. We make use of the chiral unitary approach where these two resonances appear
