CP violation in the exclusive decays B->pi(+)e(-) and B->rho e(+)e(-)

As a sequel to the calculation of the CP-violating asymmetry in the decay rates of b-->dl(+)l(-) and (b) over bar-->(d) over bar l(+)l(-). we address in this paper the asymmetry in exclusive channels (B) over bar-->pi e(+)e(-) and (B) over bar-->rho e(+)e(-), using form factors from two different models. in the invariant mass region 1 GeV<root s<M-J/psi, the partial width asymmetry in the channel (B) over bar-->pi is -6% (-2%). and that in the channel (B) over bar-->rho, for one choice of form factors, is -5% (-2%), assuming Cabibbo-Kubayashi-Maskawa parameters eta=0,34, rho=0,3 (-0,3), We also calculate the forward-backward asymmetry A(FB) of the e(-) in the e(+)e(-) center-of-mass system, and find average values [A(FB)](B-->pi)(-)=0, [A(FB)](B-rho)(-)=-17%, to he compared with the inclusive result [A(FB)](b-->d)= -9%. There is a CP-violating difference between A(FB) and the corresponding asymmetry in the antiparticle channel (A) over bar(FB) Formulas are given that are applicable to any Flavor-changing neutral current channel (B) over bar-->P-q(V-q)l(+)l(-), q=s,d, with m(l) not equal 0, including lepton spin effects. An approximate procedure is used to incorporate the rho, omega, and J/psi resonances.
