Top quarks, the most massive particles in the standard model, attract considerable attention since they decay before hadronizing. This presents physicists with a unique opportunity to directly investigate their properties. In this letter, we expand upon the work of G. Iskander, J. Pan, M. Tyler, C. Weber and O. K. Baker to demonstrate that even with the most massive fundamental particle, we see the same manifestation of entanglement observed in both electroweak and electromagnetic interactions. We propose that the thermal component resulting from protons colliding into two top quarks emerges from entanglement within the two-proton wave function. The presence of entanglement implies the coexistence of both thermal and hard scattering components in the transverse momentum distribution. We use published ATLAS and CMS results to show that the data exhibits the expected behavior.

顶夸克对产生中的量子纠缠

顶夸克是标准模型中质量最大的粒子,由于它们在强子化之前会衰变,因此引起了相当多的关注。这为物理学家提供了直接研究其性质的独特机会。在这封信中,我们扩展了 G. Iskander、J. Pan、M. Tyler、C. Weber 和 OK Baker 的工作,证明即使对于最大质量的基本粒子,我们也能看到在电弱粒子中观察到的相同的纠缠表现。和电磁相互作用。我们提出,质子碰撞两个顶夸克所产生的热分量是由双质子波函数内的纠缠产生的。纠缠的存在意味着横向动量分布中热散射分量和硬散射分量的共存。我们使用已发布的 ATLAS 和 CMS 结果来表明数据表现出预期的行为。
