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…
Electromagnetic form factors of the nucleon in chiral perturbation theory including vector mesons
Matthias R. Schindler, Jambul Gegelia, Stefan Scherer
We calculate the electromagnetic form factors of the nucleon up to fourth order in manifestly Lorentz-invariant chiral perturbation theory with vector mesons as explicit degrees of…
Quantum electrodynamics for vector mesons
D. Djukanovic, M. R. Schindler, J. Gegelia +1
Quantum electrodynamics for mesons is considered. It is shown that, at tree level, the value of the gyromagnetic ratio of the is fixed to 2 in a self-consistent effective…
Including the resonance in baryon chiral perturbation theory
C. Hacker, N. Wies, J. Gegelia +1
Baryon chiral perturbation theory with explicit degrees of freedom is considered. Using the extended on-mass-shell renormalization scheme, a manifestly Lorentz-invariant…
A new determination of the anomalous amplitude via data
I. Giller, A. Ocherashvili, T. Ebertshauser +2
We discuss the reaction with the purpose of obtaining information on the anomalous amplitude . We compare a full calculation a…
Multifragmentation, Clustering, and Coalescence in Nuclear Collisions
Stefan Scherer, Horst Stocker
Nuclear collisions at intermediate, relativistic, and ultra-relativistic energies offer unique opportunities to study in detail manifold fragmentation and clustering phenomena in d…
