论文摘要
我们与轻型喷气式喷气式飞机一起研究了重型Quarkonium（$ j/ψ$或$υ$）的包含性载体，作为QCD半硬度政权的测试场。我们的理论设置是混合的高能和共线性分解，其中标准的共线方法是通过$ t $ channel重新点燃引导能量和临时的能量对数àlabfkl的。我们介绍了关于速度和方位角差异分布的预测，在高阶校正下寻找高能序列的稳定作用。我们的反应代表了在高能量和大型横向动量下测试夸克尼亚的生产机制的附加通道，并可能阐明了从重量夸克的生产到$ j/ψ$和$υ$ state的单果碎片的过渡区域。
We investigate the inclusive hadroproduction of a heavy quarkonium ($J/ψ$ or $Υ$), in association with a light-flavored jet, as a testing ground for the semi-hard regime of QCD. Our theoretical setup is the hybrid high-energy and collinear factorization, where the standard collinear approach is supplemented by the $t$-channel resummation of leading and next-to-leading energy logarithms à la BFKL. We present predictions for rapidity and azimuthal-angle differential distributions, hunting for stabilizing effects of the high-energy series under higher-order corrections. Our reaction represents an additional channel to test the production mechanisms of quarkonia at high energies and large transverse momenta and to possibly shed light on the transition region from heavy-quark pair production to single-parton fragmentation of $J/ψ$ and $Υ$ states.
