B介子衰变中的内禀魅力

Intrinsic Charm in B-Meson Decays

S. Gardner

摘要:

轻锥强子波函数支持任意高粒子数的福克态:它们的重夸克含量通过QCD相互作用自然产生。我们讨论了强子结构所固有的c \bar c对在B介子衰变中所起的作用。这种效应在强子衰变中可能很突出,因为树能级的贡献被Cabibbo抑制了,比如B \to πK衰变,它们模仿“迷人的企鹅”的贡献。

英文摘要:

Light cone hadron wave functions support Fock states of arbitrarily high particle number: their heavy quark content arises naturally through QCD interactions. We discuss what role c\bar c pairs, intrinsic to a hadron's structure, can play in B-meson decays. The effects can be prominent in hadronic decays for which the tree-level contributions are Cabibbo-suppressed, as in B\to πK decay, and they mimic ``charming penguin'' contributions.
