论文摘要
研究了使用小$ x $ x $ $ k_t $ - factorization在高能$ pp $碰撞下生产的hadrons $ p_t $光谱中的几何缩放。它提出了一个现象学参数化，用于缩放范围内未集成的Gluon分布，该参数在饱和和稀释的扰动QCD方案中又重现了差分横截面的特征。由于饱和度量表是红外区域（IR）的有效调节剂，因此研究了该模型通常与软物理相关的数量。该方法用于计算平均$ P_T $和高能生产的胶子的速度分布。
The presence of geometric scaling within the $p_T$ spectra of produced hadrons at high energy $pp$ collisions using small-$x$ $k_T$-factorization is investigated. It is proposed a phenomenological parameterization for the unintegrated gluon distribution in the scaling range which reproduces the features of the differential cross section both in the saturated and dilute perturbative QCD regimes. As the saturation scale acts as an effective regulator of the infrared region (IR), the extension of the model to quantities usually associated to soft physics is studied. The approach is applied to compute the average $p_T$ and the rapidity distribution of produced gluons at high energies.
