Recent Theoretical Studies on Hadronic Atoms
A. N. Ivanov, M. Cargnelli, M. Faber +5
A report contains a review of recent theoretical investigations on kaonic atoms carried out at Stefan Meyer Institute of the Austrian Academy of Sciences. We discuss (1) a phenomen…
On kaonic hydrogen. Phenomenological quantum field theoretic model revisited
A. N. Ivanov, M. Cargnelli, M. Faber +5
We argue that due to isospin and U-spin invariance of strong low-energy interactions the S-wave scattering lengths a^0_0 and a^1_0 of bar-KN scattering with isospin I=0 and I = 1 s…
On isospin-breaking corrections to the energy level displacement of the ground state of kaonic hydrogen
A. N. Ivanov, M. Cargnelli, M. Faber +5
In the model of low-energy bar-K N interactions near threshold (EPJA 21, 11 (2004); 25, 79 (2005)) we calculate isospin-breaking corrections to the energy level displacement of the…
On radiative np -> 1s + gamma transitions, induced by strong low-energy interactions,in kaonic atoms
A. N. Ivanov, M. Cargnelli, M. Faber +5
We calculate the rates of the radiative transitions np -> 1s + gamma in kaonic hydrogen and kaonic deuterium, induced by strong low-energy interactions and enhanced by Coulomb inte…
Energy level displacement of excited np states of kaonic hydrogen
A. N. Ivanov, M. Cargnelli, M. Faber +5
We compute the energy level displacement of the excited np states of kaonic hydrogen within the quantum field theoretic and relativistic covariant model of strong low-energy bar-KN…
On kaonic deuterium. Quantum field theoretic and relativistic covariant approach
A. N. Ivanov, M. Cargnelli, M. Faber +5
We study kaonic deuterium, the bound K^-d state A_(K d). Within a quantum field theoretic and relativistic covariant approach we derive the energy level displacement of the ground…
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…
