强子光-光耦合对μ介子g-2的贡献

The Hadronic Light-by-Light Contribution to Muon g-2: A Short Review

Joaquim Prades

摘要:

我回顾了强子逐光散射对μ子g-2的贡献的最新计算和现状。特别地,我讨论了最近与Eduardo de Rafael和Arkady Vainshtein一起工作中获得的主要结果,其中我们得到了估计a^{ \rm HLbL}_μ=(10.5 +- 2.6)x 10^{-10}。本文还强调了低能装置的双光子物理计划如何有助于减少目前的模型依赖。

英文摘要:

I review the recent calculations and current status of the hadronic light-by-light scattering contribution to muon g-2. In particular, I discuss the main results obtained in a recent work together with Eduardo de Rafael and Arkady Vainshtein where we came to the estimate a^{\rm HLbL}_μ= (10.5 +- 2.6) x 10^{-10}. How the two-photon physics program of low energy facilities can help to reduce the present model dependence is also emphasized.
