我们研究了源自强子波函数中胶子量子性质的相关性。相同粒子之间的玻色-爱因斯坦关系导致具有相同量子数和较小相对动量的胶子对数量的增加。我们证明这些预先存在的相关性可以在高能的深非弹性散射实验中探测到。具体来说，我们考虑衍射双射流加上第三射流生产。在光子射流的横向动量不平衡与强子射流的横向动量不平衡之间的零相对角处，方位角依赖性达到峰值。我们的计算清楚地表明，峰值来自玻色增强。比较电子-质子和电子-核碰撞，我们证明了核靶增强了峰的相对强度。在未来的高光度电子-离子对撞机中，提出的胶子玻色增强测量方法在实验上是可行的。
We study correlations originating from the quantum nature of gluons in a hadronic wave function. Bose-Einstein correlation between identical particles lead to the enhancement in the number of pairs of gluons with the same quantum numbers and small relative momentum. We show that these preexisting correlations can be probed in deep inelastic scattering experiments at high energy. Specifically, we consider diffractive dijet plus a third jet production. The azimuthal dependence displays a peak at the zero relative angle between the transverse momentum imbalance of the photon-going dijet and the transverse momentum of the hadron-going jet. Our calculations explicitly show that the peak originates from Bose enhancement. Comparing electron-proton to electron-nucleus collisions, we demonstrate that the nuclear target enhances the relative strength of the peak. With the future high luminosity electron-ion collider the proposed measurements of gluon Bose enhancement become experimentally feasible.
