摘要

在这项工作中，我们使用低能EFT来分析cLFV过程，该过程诱导两个不同风味的带电轻子与两个光子之间的有效相互作用。我们计算了i→jγ， i→jγ衰变和i→jγ在原子核中的转换。我们推导了双光子衰变的间接上限，结果表明该上限低于目前的实验边界。我们对原子核中r→τ转换的预测低于NA64实验的预期灵敏度

Study of cLFV with ℓiℓjγγ effective vertex

In this work we analyze cLFV processes using a low-energy EFT that induces the effective interaction between two charged leptons of different flavor and two photons. We compute ℓi → ℓjγ, ℓi → ℓjγγ decays and ℓi → ℓj conversion in nuclei. We derived indirect upper limits on the double photon decays, which turned out to be below current experimental bounds. Our prediction for ℓ → τ conversion in nuclei is below the expected sensitivity of the NA64 experiment
