Energy level displacement of the excited nl state of pionic hydrogen
A. N. Ivanov, M. Faber, A. Hirtl +2
The energy level displacements of the excited nl states of pionic hydrogen and the contribution of the ns -> 1s transitions and the (pi^-p)_Coul -> 1s transitions of the pi^-p pair…
Center Dominance in SU(2) Gauge-Higgs Theory
Roman Bertle, Manfried Faber, Jeff Greensite +1
We study the SU(2) gauge-Higgs system in D=4 dimensions, and analyze the influence of the fundamental-representation Higgs field on the vortex content of the gauge field. It is sho…
On kaonic hydrogen. Quantum field theoretic and relativistic covariant approach
A. N. Ivanov, M. Cargnelli, M. Faber +3
We study kaonic hydrogen, the bound K^-p state A_(Kp). Within a quantum field theoretic and relativistic covariant approach we derive the energy level displacement of the ground st…
New Family of Exotic -Baryons
Dmitry Borisyuk, Manfried Faber, Alexander Kobushkin
From the interpretation of the baryon resonance as an excitation of the ``skyrmion liquid'' with SU(3) flavor symmetry we deduce a new series of baryons, $Θ_1^{++}…
On pionic hydrogen. Quantum field theoretic, relativistic covariant and model-independent approach
A. N. Ivanov, M. Faber, A. Hirtl +2
We consider pionic hydrogen A_(pi p), the bound pi^- p state. Within the quantum field theoretic and relativistic covariant approach we calculate the shift and width of the energy…
On the vacua in the massless Thirring model
M. Faber, A. N. Ivanov
We calculate the most general effective potential for the massless Thirring model in dependence of the local fields of all fermion-antifermion collective excitations. We analyse th…
