AI总结:

该研究探讨了胶子 Bose 增强对核波函数中不相干衍射双喷注产生截面的影响,发现当喷注横向动量对齐时截面增强,且在动量大小相等时达到最大。

摘要:

我们研究了胶子 Bose 增强对核波函数中不相干衍射双喷注产生的影响。我们证明,当两个喷注的横向动量在相对角度上对齐为零时,Bose 增强会导致衍射双喷注产生截面的增强。这种增强在两个喷注的横向动量大小相等时达到最大值,并且随着两个动量比的变化而迅速消失。我们研究了稀疏极限和完全非线性密集区域,在这两种情况下,核波函数都通过主导阶 JIMWLK 方程进行演化。在两种情况下我们都观察到可见的影响,这种影响由于色中性化尺度的动态生成而增强。

英文摘要:

We investigate the effect of gluon Bose enhancement in the nuclear wave function on the dijet production in incoherent diffractive processes in DIS and ultraperipheral collisions. We demonstrate that Bose enhancement leads to an enhancement of diffractive dijet production cross section when the transverse momenta of the two jets are aligned at zero relative angle. This enhancement is maximal when the magnitude of the transverse momenta of the two jets are equal, and disappears rather quickly as a function of the ratio of the two momenta. We study both the dilute limit and fully nonlinear dense regime where the nuclear wave function is evolved with the leading order JIMWLK equation. In both cases we observe a visible effect, with it being enhanced by the evolution due to the dynamical generation of the color neutralization scale.
