Abstract

We discuss the semileptonic B decays of the form B→J/ψevX as possible probes of intrinsic charm. We calculate the leading order perturbative contribution to the process B→J/ψe-eX and find it to be unobservably small, with a branching ratio ∼ 10-10. We propose a modified spectator model to estimate the intrinsic charm contribution and find that it can be significantly larger, with a branching ratio for B→(cc̄)e-eX as large as 5×10-7. We show that the process could be observed at these levels by the Collider Detector at Fermilab assuming a run II integrated luminosity of 15 fb-1, making this a useful reaction to probe the idea of intrinsic charm.
