近阈值电子-正电子湮灭对强引力的限制

Bounds to strong gravity from electron-positron annihilations near threshold

Nathaniel Alden, Roberto Onofrio

AI总结:

本文利用近阈值电子-正电子湮灭及大质量粒子产生截面增强,分析 W 玻色子对和重轻子对过程对强引力的限制,并指出未来对撞机可改进这些与引力子直接探测互补的约束。

摘要:

我们讨论了由电子和正电子湮灭以及相应的大质量粒子产生截面增强所带来的对强引力的限制。文中讨论了两个互补的例子:一是 e^+e^- → W^+W^- 过程,其末态粒子对具有最大质量和较短寿命;二是电子-正电子湮灭为更重带电轻子对的情形,即 e^+e^- → μ^+μ^- 和 e^+e^- → τ^+τ^-。这些限制有望通过下一代电子-正电子对撞机得到改进,并与直接寻找引力子所得的限制形成互补。

英文摘要:

We discuss bounds to strong gravity arising from annihilation of electron and positrons and the corresponding enhancement of the cross section for the production of massive particles. Two complementary examples are discussed, the case of the $e^+e^- \to W^+ W^-$ processes, with maximum mass and short lifetime for the particle pairs in the final state, and the case of electron positron annihilation into heavier charged lepton pairs, $e^+ e^- \to μ^+ μ^-$ and $e^+ e^- \to τ^+ τ^-$. These bounds may be improved by the next generation of electron-positron colliders, and are complementary to bounds arising from direct graviton searches.
