我们提出了一个新的决议，几十年来的神秘，发生了什么事时，正电子散射了最小的大统一理论在s波，一个谜首先讨论的卡兰在1983年。使用语言的壳振幅和成对螺旋度，我们建议，最终状态包含两个上夸克和一个下夸克在纠缠的“成对”多粒子状态，唯一的粒子最终状态，满足角动量和规范电荷守恒。这个过程的截面与原来的Rubakov-Callan效应一样大，只是被QCD尺度所抑制。我们发现的最终状态在Callan的截断2D理论中是看不到的，因为我们的新的成对状态只出现在二维以上。
We suggest a novel resolution for a decades old mystery—what happens when a positron scatters off a minimal grand-unification-theory monopole in an s wave, a puzzle first discussed by Callan in 1983. Using the language of on shell amplitudes and pairwise helicity we suggest that the final state contains two up quarks and a down quark in an entangled “pairwise” multiparticle state—the only particle final state that satisfies angular momentum and gauge charge conservation. The cross section for this process is as large as in the original Rubakov-Callan effect, only suppressed by the QCD scale. The final state we find cannot be seen in Callan’s truncated 2D theory, since our new pairwise state appears only in more than two dimensions.
