Abstract

By using very general and well established features of soft strong interactions we show, contrary to conventional expectations, that (i) soft final-state interactions (FSI) do not disappear for large m_B, (ii) inelastic rescattering is expected to be the main source of soft FSI phases, and (iii) FSI which interchange charge and/or flavors are suppressed by a power of m_B, but are quite likely to be significant at m_B\ensuremath≃5GeV. We briefly discuss the influence of these interactions on tests of CP violation and on theoretical calculations of weak decays.
