用光锥QCD求和规则分析$Λ_b \to Λ_c$跃迁的Isgur-Wise函数

Analysis of the Isgur-Wise function of the $Λ_b \to Λ_c$ transition with light-cone QCD sum rules

Zhi-Gang Wang

摘要:

本文利用光锥QCD求和规则,将$Λ_b$重子光锥分布振幅与$Λ_b \to Λ_c$跃迁的Isgur-Wise函数$ξ(ω)$联系起来,得到一个简单的关系式. Isgur-Wise函数$ξ(ω)$的数值与QCD求和规则的预言是一致的。

英文摘要:

In this article, we use the light-cone QCD sum rules to relate the $Λ_b$ baryon light-cone distribution amplitudes to the Isgur-Wise function $ξ(ω)$ of the $Λ_b \to Λ_c$ transition, and obtain a simple relation. The numerical value of the Isgur-Wise function $ξ(ω)$ is consistent with the prediction of the QCD sum rules.
