Nucleon deformation in finite nuclei
U. T. Yakhshiev, M. M. Musakhanov, A. M. Rakhimov +2
The deformation of a nucleon embedded in various finite nuclei is considered by taking into account the distortion of the chiral profile functions under the action of an external f…
In-medium chiral perturbation theory beyond the mean-field approximation
Ulf-G. Meißner, José A. Oller, Andreas Wirzba
An explicit expression of the generating functional of two-flavor low-energy QCD with external sources in the presence of non-vanishing nucleon densities has been derived recently…
Wave Chaos in Elastodynamic Cavity Scattering
Andreas Wirzba, Niels Sondergaard, Predrag Cvitanovic
The exact elastodynamic scattering theory is constructed to describe the spectral properties of two- and more-cylindrical cavity systems, and compared to an elastodynamic generaliz…
Instantons As Unitary Spin Maker
Mauro Napsuciale, Andreas Wirzba, Mariana Kirchbach
We investigate the relevance of the instanton-induced determinantal 't Hooft interaction to the eta-nucleon coupling within the framework of a three-flavor linear sigma model in th…
Self energies of the pion and the delta isobar from the ^3He(e,e'pi^+)^3H reaction
M. Kohl, M. Kuss, C. Rangacharyulu +7
In a kinematically complete experiment at the Mainz microtron MAMI, pion angular distributions of the He(e,e'H reaction have been measured in the excitation region of t…
Casimir Interaction among Objects Immersed in a Fermionic Environment
Aurel Bulgac, Andreas Wirzba
Using ensembles of two, three and four spheres immersed in a fermionic background we evaluate the (integrated) density of states and the Casimir energy. We thus infer that for suff…
