Operator product expansion for exclusive decays B+-> D(s)(+)e(+)e(-) and B+-> D(s)(*+)e(+)e(-)

proceed through a weak and an electromagnetic The decays B+ --> D-s(+),(d)e (+)e(-) and B+ --> D-s,D-d*(+)e(+)e(-) interaction. This is a typical "long distance" process, usually difficult to compute systematically. We propose that over a large fraction of phase space a combination of operator produc t and heavy quark expansions effectively turns this process into one in whi ch the weak and electromagnetic interactions occur through a local operator . Moreover, we use heavy quark spin symmetry to relate all the local operat ors that appear in leading order of the operator expansion to two basic one s. We use this operator expansion to estimate the decay rates for B+ --> D- s,d(()*()+)e(+)e(-) .
