Systematics of soft final state interactions in $B$ decay

High Energy Physics - Phenomenology 2009-10-28 v1

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 mBm_B, (ii) inelastic rescattering is expected to be the main source of soft FSI phases, and (iii) flavor off-diagonal FSI are suppressed by a power of mBm_B, but are quite likely to be significant at mB5m_B\simeq 5~GeV. We briefly discuss the influence of these interactions on tests of CP-violation and on theoretical calculations of weak decays.
