Direct CP violation in b {yields} dJ/{psi} decays

Abstract

We investigate the possibility of observing direct CP violation in self-tagging B-meson decays of the type b {yields} dJ/{psi}. The CP asymmetry can be generated due to strong or electromagnetic scattering in the final state, or due to long distance effects. The first two contributions give asymmetries of a few x 10{sup -3}, in the standard model. The long distance effects are hard to estimate, but it cannot be excluded that they yield asymmetries of about 1%. (author). 16 refs.
