We investigate the effect of soft gluon radiations on the azimuthal angle correlation between the total and relative momenta of two jets in inclusive and exclusive dijet processes. We show that the final state effect induces a sizable cos(2ϕ) anisotropy due to gluon emissions near the jet cones. The phenomenological consequences of this observation are discussed for various collider experiments, including diffractive processes in ultraperipheral pA and AA collisions, inclusive and diffractive dijet production at the EIC, and inclusive dijet in pp and AA collisions at the LHC.
我们研究了软胶子辐射对包容性和排他性双喷注过程中两个喷注的总动量与相对动量之间方位角关联的影响。我们表明，末态效应由于喷注锥附近的胶子发射而导致可观的cos(2ϕ)各向异性。针对各种对撞机实验讨论了这一观测结果的唯象学后果，包括超外围pA和AA碰撞中的衍射过程、电子离子对撞机上的包容性和衍射性双喷注产生，以及大型强子对撞机上pp和AA碰撞中的包容性双喷注。
