低能电子-核子和电子-核散射中μ子的产生

Muon production in low-energy electron-nucleon and electron-nucleus scattering

Prashanth Jaikumar, Daniel R. Phillips, Lucas Platter, Madappa Prakash

摘要:

最近,电子-质子散射中μ子的产生被认为是一种可能的候选反应,用于识别由于标准模型之外的物理引起的轻子味破坏。本文指出标准模型过程$e^- p \to μ^- p \barν_μν_e$和$e^- p \to e^- n μ^+ ν_μ$可以使电子-质子碰撞中的标准模型以外的势信号变得模糊。我们发现标准模型$e p \to μX$的截面比轻子味违反算子的截面大几个数量级。我们还讨论了使用核靶来增强$e p \to μX$信号的可能性。

英文摘要:

Recently, muon production in electron-proton scattering has been suggested as a possible candidate reaction for the identification of lepton-flavor violation due to physics beyond the Standard Model. Here we point out that the Standard-Model processes $e^- p \to μ^- p \barν_μν_e$ and $e^- p \to e^- n μ^+ ν_μ$ can cloud potential beyond-the-Standard-Model signals in electron-proton collisions. We find that Standard-Model $e p \to μX$ cross sections exceed those from lepton-flavor-violating operators by several orders of magnitude. We also discuss the possibility of using a nuclear target to enhance the $e p \to μX$ signal.
