EFT中$ΛN \to NN$跃迁的单圈贡献

One-loop contributions in the EFT for the $ΛN \to NN$ transition

Axel Pérez-Obiol, David R. Entem, Bruno Juliá-Díaz, Assumpta Parreño

摘要:

我们认为$ΛN\to NN$弱跃迁是超核非介子弱衰变的主要原因。我们遵循先前推导的有效场论,并计算次领先的单圈修正。提供了所有图的显式表达式,从而导致对所有相关分波的贡献。

英文摘要:

We consider the $ΛN\to NN$ weak transition, responsible for a large fraction of the non-mesonic weak decay of hypernuclei. We follow on the previously derived effective field theory and compute the next-to-leading one-loop corrections. Explicit expressions for all diagrams are provided, which result in contributions to all relevant partial waves.
