Manifestly Lorentz-Invariant Baryon Chiral Perturbation Theory

Stefan Scherer

A successful effective field theory program requires besides the most general effective Lagrangian a perturbative expansion scheme for observables in terms of a consistent power co…

Quantum electrodynamics for vector mesons

D. Djukanovic, M. R. Schindler, J. Gegelia +1

Quantum electrodynamics for $ρ$ mesons is considered. It is shown that, at tree level, the value of the gyromagnetic ratio of the $ρ^{+}$ is fixed to 2 in a self-consistent effective…

Including the $Δ (1232)$ resonance in baryon chiral perturbation theory

C. Hacker, N. Wies, J. Gegelia +1

Baryon chiral perturbation theory with explicit $Δ (1232)$ degrees of freedom is considered. Using the extended on-mass-shell renormalization scheme, a manifestly Lorentz-invariant…

A new determination of the $γ π \to π π$ anomalous amplitude via $π^{-} e^{-} \to π^{-} e^{-} π^{0}$ data

I. Giller, A. Ocherashvili, T. Ebertshauser +2

We discuss the reaction $π^{-} e^{-} \to π^{-} e^{-} π^{0}$ with the purpose of obtaining information on the $γ π \to π π$ anomalous amplitude $F_{3 π}$ . We compare a full calculation a…
