标题： Entanglement Enabled Intensity Interferometry in ultrarelativistic ultraperipheral nuclear collisions

摘要： 研究超相对论重离子碰撞中物质亚费米尺度时空结构的重要工具是最终态中相同粒子的Hanbury-Brown-Twiss (HBT)强度干涉测量法。 我们在这里表明，Cotler和Wilczek提出的一种基于量子纠缠的强度干涉测量法（$E^2 I^2$）为提取高能QCD的基本非微扰特性提供了一种强大的替代方法。 特别是，我们表明，核子中色单态（pomeron）构型的空间分布可以通过$\rho$-介子在RHIC和LHC的超相对论超外围核碰撞（UPCs）中独产生共振衰变为$\pi^\pm$-对来获得。 这里开发的$E^2 I^2$框架非常通用。 它可以用来提取pomeron耦合自旋结构的信息，并且可以增强在UPCs以及电子-离子对撞机上通过矢量介子独生衰变到少粒子末态来发现稀有odderon构型的可能性。 显示英文摘要

摘要： An important tool in studying the sub-femtoscale spacetime structure of matter in ultrarelativistic heavy-ion collisions is Hanbury-Brown-Twiss (HBT) intensity interferometry of identical particles in the final state of such collisions. We show here that a variant of an entanglement enabled intensity interferometry ($E^2 I^2$) proposed by Cotler and Wilczek provides a powerful alternative to HBT interferometry in extracting fundamental nonperturbative features of QCD at high energies. In particular, we show that the spatial distributions of color singlet (pomeron) configurations in nuclei can be obtained from exclusive resonant decays of $\rho$-mesons into $\pi^\pm$-pairs in ultrarelativistic ultraperipheral nuclear collisions (UPCs) at RHIC and the LHC. The $E^2 I^2$ framework developed here is quite general. It can be employed to extract information on the spin structure of pomeron couplings as well as enhance the discovery potential for rare odderon configurations from exclusive vector meson decays into few-particle final states both in UPCs and at the Electron-Ion Collider.
