Decay widths and energy shifts of pi pi and pi K atoms | J. Schweizer
; | Date: |
9 Dec 2003 | Journal: | Phys.Lett. B587 (2004) 33-40 | Subject: | hep-ph | Affiliation: | Bern University | Abstract: | We calculate the S-wave decay widths and energy shifts for pi pi and pi K atoms in the framework of QCD+QED. The evaluation - valid at next-to-leading order in isospin symmetry breaking - is performed within a non-relativistic effective field theory. The results are of interest for future hadronic atom experiments. | Source: | arXiv, hep-ph/0401048 | Services: | Forum | Review | PDF | Favorites |
