Neutrino mediated muon--electron conversion in nuclei revisited
F. Simkovic, V. E. Lyubovitskij, Th. Gutsche +2
The non-photonic neutrino exchange mechanism of the lepton flavor violating muon-electron conversion in nuclei is revisited. First we determine the nucleon coupling constants for t…
Neutron-Proton High-Energy Charge Exchange Scattering
Y. Yan, R. Tegen, T. Gutsche +2
The high energy proton-neutron charge exchange scattering reaction is studied in an effective hadron model for the energy range of s from 45.9 to 414.61 GeV*GeV. The main features…
Hadronic potentials from effective field theories
E. Lipartia, V. E. Lyubovitskij, A. Rusetsky
We construct the potentials that describe the spectrum and decay of electromagnetic bound states of hadrons, and are consistent with ChPT. These potentials satisfy the matching con…
piN scattering and electromagnetic corrections in the perturbative chiral quark model
V. E. Lyubovitskij, Th. Gutsche, Amand Faessler +1
We apply the perturbative chiral quark model to give predictions for the electromagnetic O(p^2) low-energy couplings of the ChPT effective Lagrangian that define the electromagneti…
Electromagnetic couplings of the ChPT Lagrangian from the perturbative chiral quark model
V. E. Lyubovitskij, Th. Gutsche, Amand Faessler +1
We apply the perturbative chiral quark model to the study of the low-energy pi-N interaction. Using an effective chiral Lagrangian we reproduce the Weinberg-Tomozawa result for the…
Semileptonic decays of double heavy baryons
Amand Faessler, Th. Gutsche, M. A. Ivanov +2
We study the semileptonic decays of the lowest lying double heavy baryons using the relativistic three-quark model. We do not employ a heavy quark mass expansion but keep the masse…
Nucleon Properties in the Perturbative Chiral Quark Model
V. E. Lyubovitskij, Th. Gutsche, Amand Faessler
We apply the perturbative chiral quark model (PCQM) to analyse low-energy nucleon properties: electromagnetic form factors, meson-nucleon sigma-terms and pion-nucleon scattering. B…
Electromagnetic Structure of the Nucleon in the Perturbative Chiral Quark Model
V. E. Lyubovitskij, Th. Gutsche, Amand Faessler
We apply the perturbative chiral quark model (PCQM) at one loop to analyse the electromagnetic structure of nucleons. This model is based on an effective Lagrangian, where baryons…
Decays of the pi+ pi- atom
J. Gasser, V. E. Lyubovitskij, A. Rusetsky +1
We construct an effective non-relativistic quantum field theory that describes bound states of pi+ pi- pairs and their hadronic decays. We then derive a general expression for the…
