Spectrum and decays of hadronic atoms
We describe the spectra and decays of π+π- and π±K∓ atoms within a non-relativistic effective field theory. The evaluations of the energy shifts and widths are performed at next-to-leading order in isospin symmetry breaking. The prediction for the lifetime of the π±K∓ atom in its ground-state yields τ10=(3.7±0.4)·10-15s.
