Off-shell electromagnetic form factors of pions and kaons in chiral perturbation theory.
The off–shell electromagnetic vertex of a (pseudo–) scalar particle contains, in general, two form factors F and G which depend, in addition to the squared momentum transfer, on the invariant masses associated with the initial and final legs of the vertex. Chiral perturbation theory to one loop is used to calculate the off–shell form factors of pions and kaons. The formalism of Gasser and Leutw...
متن کاملElectromagnetic mass differences of pions and kaons
We use the Cottingham method to calculate the pion and kaon electromagnetic mass differences with as few model dependent inputs as possible. The constraints of chiral symmetry at low energy, QCD at high energy and experimental data in between are used in the dispersion relation. We find excellent agreement with experiment for the pion mass difference. The kaon mass difference exhibits a strong ...
متن کاملKaons and pions in strange quark matter
The behavior of kaons and pions in strange quark matter in weak equilibrium, is investigated within the SU(3) Nambu-Jona-Lasinio [NJL] model. This work focuses a region of high densities where the behavior of mesons has not been explored in the framework of this model. It is found that above the density where strange valence quarks appear in the medium, ρ = 3.8ρ0, a change of behavior of differ...
متن کاملOff-shell pions in the BUU transport theory
Due to the large resonance πN scattering cross section a pion with momentum ∼ 0.3 GeV/c acquires a width in nuclear matter. The pion spectral function in nuclear matter is, therefore, different from the vacuum one. The present work is the first attempt to include the pion spectral function into the BUU transport theory. We have calculated the pion polarization function Πc(k) in isospin symmetri...
متن کاملElectromagnetic Corrections for Pions and Kaons : Masses and Polarizabilities
The unknown constants in Chiral Perturbation Theory needed for an all orders analysis of the polarizabilities and electromagnetic corrections to the masses of the pseudo-Goldstone bosons are estimated at leading order in 1/Nc. We organize the calculation in an 1/Nc-expansion and separate longand short-distance physics contributions by introducing an Euclidean cut-off. The long-distance part is ...
