Abstract: (arXiv)
The effects due to soft-photon emission (and the related virtual corrections) in multi-body decays of B, D, and K mesons are analysed. We present analytic expressions for the universal O(alpha) correction factors which can be applied to all multi-body decay modes where a tight soft-photon energy cut in the decaying-particle rest-frame is applied. All-order resummations valid in the limit of small and large velocities of the final-state particles are also discussed. The phenomenological implications of these correction factors in the distortion of Dalitz-plot distributions of K -> 3 pi decays are briefly analysed.- meson: hadronic decay
- meson: multiple production
- photon: emission
- B: hadronic decay
- D: hadronic decay
- K: hadronic decay
- meson: width
- differential cross section: radiative correction
- Dalitz plot
- numerical calculations
