Poles in scattering from forward dispersion relations and revised total cross-section data
José Ramón Peláez, Pablo Rabán, Jacobo Ruiz de Elvira
We present a model-independent calculation of forward dispersion relations and their analytic continuation to the complex plane, using a revised set of total cross-s…
Structure of the lightest scalar meson from the 1/Nc expansion of Unitarized Chiral Perturbation Theory and Regge Theory
J. Ruiz de Elvira, J. R. Pelaez, M. R. Pennington +1
One-loop unitarized Chiral Perturbation Theory (UChPT) calculations, suggest a different Nc behaviour for the sigma or f_0(600) and rho(770) mesons: while the rho meson becomes nar…
The effect of isospin violation on scalar meson production
C. Hanhart, B. Kubis, J. R. Pelaez
We investigate the isospin-violating mixing of the light scalar mesons a0(980) and f0(980) within the unitarized chiral approach. Isospin-violating effects are considered to leadin…
Thermal rho and sigma mesons from chiral symmetry and unitarity
A. Dobado, A. Gomez Nicola, F. J. Llanes-Estrada +1
We study the temperature evolution of the rho and sigma mass and width, using a unitary chiral approach. The one-loop pion-pion scattering amplitude in Chiral Perturbation Theory a…
Report of the Working Group on Goldstone Bosons
Johan Bijnens, Ada Farilla, Rory Miskimen
An overview is presented of the talks in the working group on Goldstone Bosons. Topics touched on are CP-violation in the Kaon system, rare Kaon decays, -scattering, -meson…
LHC sensitivity to the resonance spectrum of a minimal strongly interacting electroweak symmetry breaking sector
A. Dobado, M. J. Herrero, J. R. Pelaez +1
We present a unified analysis of the two main production processes of vector boson pairs at the LHC, VV-fusion and qqbar annihilation, in a minimal strongly interacting electroweak…
The phi to pi+ pi- decay within a chiral unitary approach
J. A. Oller, E. Oset, J. R. Pelaez
Starting from the Chiral Perturbation Theory Lagrangian, but keeping different masses for the charged and neutral mesons, and using a previously developed non-perturbative unitary…
SU(3) Chiral approach to meson and baryon dynamics
E. Oset, A. Hosaka, J. C. Nacher +6
We report on recent progress on the chiral unitary approach, which is shown to have a much larger convergence radius than ordinary chiral perturbation theory, allowing one to repro…
The Hadronic Gas Chiral Phase Transition within Generalized Chiral Perturbation Theory
J. R. Pelaez
We study the temperature evolution of the quark-antiquark condensate below the chiral phase transition. The hadronic gas is described using a virial expansion within Generalized Ch…
The Applicability of the Equivalence Theorem in
A. Dobado, J. R. Pelaez, M. Urdiales
We have explicitely calculated the tree level elastic scattering cross sections of two longitudinal gauge bosons, up to four derivatives in the chiral expansion both with and witho…
