摘要：

The rare semileptonic B-meson decay B -> I center dot a""(+)a""(-) is considered. The partial decay rate integrated over the 1-8 GeV2 interval of the dilepton invariant mass squared is computed with a 10% systematic uncertainty arising from the model dependence of the distribution amplitude. The purely perturbative contribution to the decay probability amounts to a"notsign similar to 10(-12), which suggests that the LHC experiments could observe the B -> I center dot a""(+)a""(-) decay in a few years of data taking.
