Probing for the charm content of B and [Formula Presented] mesons

Research output: Contribution to journalArticle

Abstract

A slow (Formula presented) bump exists in the inclusive (Formula presented) spectrum, while the softness of the (Formula presented) spectrum in (Formula presented) decay is in strong contrast to expectations from the color octet mechanism. We propose intrinsic charm as the explanation: the former is due to (Formula presented) with three charm quarks in the final state; the latter is just a small fraction of (Formula presented) “jet” events, where the slow moving (Formula presented) system evolves into (Formula presented) pairs. An experimental search for these phenomena at B factories and the Fermilab Tevatron is strongly urged, as the implications go beyond QCD.
