Open AccessRedetermination of the strong-interaction width in pionic hydrogen
The hadronic width of the ground state of pionic hydrogen has been redetermined by X-ray spectroscopy to be $$\varGamma ^{\pi \mathrm {H}}_{1s...

Hadronic shift in pionic hydrogen
The hadronic shift in pionic hydrogen has been redetermined to be ε 1s = 7.086 ± 0.007(stat) ± 0.006(sys) eV by X-ray spectroscopy of ground-state transitions applying various ene...

Precision measurement of the (3p–1s) X-ray transition in muonic hydrogen
The (3p — 1s) X-ray transition to the muonic hydrogen ground state was measured with a highresolution crystal spectrometer. The assumption of a statistical population of the hyperfine levels of the muonic hydroge...

On kaonic hydrogen. Phenomenological quantum field theoretic model revisited
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 ¯N scattering with isospin I = 0 and I = 1 satisfy the low-energy theorem a 0

From solar proton burning to pionic deuterium through the Nambu-Jona-Lasinio model of light nuclei
Within the Nuclear Nambu-Jona-Lasinio model of light nuclei (the NNJL model), describing strong low-energy nuclear interactions, we compute the width of the energy level of the ground state of pionic deuterium...

On kaonic deuterium. Quantum field-theoretic and relativistic covariant approach
We study kaonic deuterium, the bound K-d state AK d. Within a quantum field-theoretic and relativistic covariant approach we derive the energy level displacement of the ground state of kaonic deuterium in terms o...
