James Chadwick: ahead of his time
Gerhard Ecker
James Chadwick is known for his discovery of the neutron. Many of his earlier findings and ideas in the context of weak and strong nuclear forces are much less known. This biograph…
Status of chiral perturbation theory for light mesons
Gerhard Ecker
The status of chiral perturbation theory in the meson sector is illustrated with several topical examples. The longtime discrepancy between theory and experiment for the charged pi…
Mesonic low-energy constants
Johan Bijnens, Gerhard Ecker
We review the status of the coupling constants of chiral Lagrangians in the meson sector, the so-called low-energy constants (LECs). Special emphasis is put on the chiral a…
Facets of chiral perturbation theory
Gerhard Ecker
Chiral perturbation theory is the effective field theory of the Standard Model at low energies. After a short introduction and overview, I discuss three topics where the chiral app…
Approximating chiral SU(3) amplitudes
G. Ecker, P. Masjuan, H. Neufeld
We construct large-N_c motivated approximate chiral SU(3) amplitudes of next-to-next-to-leading order. The amplitudes are independent of the renormalization scale. Fitting lattice…
Kaon Decays in the Standard Model
V. Cirigliano, G. Ecker, H. Neufeld +2
A comprehensive overview of kaon decays is presented. The Standard Model predictions are discussed in detail, covering both the underlying short-distance electroweak dynamics and t…
