QCD Short-distance Constraints and Hadronic Approximations
Johan Bijnens, Elvira Gamiz, Edisher Lipartia +1
This paper discusses a general class of ladder resummation inspired hadronic approximations. It is found that this approach naturally reproduces many successes of single meson per…
Ground-state energy of pionic hydrogen to one loop
J. Gasser, M. A. Ivanov, E. Lipartia +2
We investigate the ground-state energy of the pi- p atom (pionic hydrogen) in the framework of QCD+QED. In particular, we evaluate the strong energy-level shift. We perform the cal…
Effective Field Theoretical Approach to Black Hole Production
Sven Bilke, Edisher Lipartia, Martin Maul
A field theoretical description of mini black hole production at TeV energies is given taking into account the quantization of black holes in discrete resonances. The unknown quant…
Theory of the pi+ pi- atom
M. A. Ivanov, V. E. Lyubovitskij, E. Z. Lipartia +1
The relativistic perturbative approach based on the Bethe-Salpeter (BS) equation is developed for the study of the characteristics of the hadronic pi+ pi- atom. The general express…
Wu-Yang Monopole with a Topological "Charge"
S. Gogilidze, N. Ilieva, E. Lipartia +1
The paper has been withdrawn for further elaboration.
pi+pi- Atom in Chiral Theories
M. A. Ivanov, V. E. Lyubovitskij, E. Z. Lipartia +1
We review the existing theoretical approaches to the study of the observables of hadronic atoms. In the relativistic perturbative approach based on the Bethe-Salpeter equation and…
