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…

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…

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…
