论文摘要
我们提出$ O（α_s）$分析性预测事件形状的1杰t $τ_1$分配瞄准在未来电子离子校友处深度非弹性散射过程中的分布瞄准。结果取决于传统变量$ x $和$ q $以及$τ_1$，并且相对紧凑且易于实现数值计算。在BREIT框架中考虑了$τ_1$的三种不同选择的轴。第一个是对最小化$τ_1$进行最佳调整的一种，第二和第三是从抗$ k_t $和Centauro Jet算法中分别取决于Jet Radius Parameter $ r $。我们发现，第一个和第二个在此订单下给出相同的结果，并且独立于$ r $，而第三个取决于半径。该固定订单结果提供了非贡献的贡献，可以与单一的日志示点贡献相结合，以提供$τ_1$空间的完整频谱，还显示了固定顺序和重新点燃区域如何随着$ x $和$ q $的函数而变化。
We present $O(α_s)$ analytic predictions for event shape 1-jettiness $τ_1$ distribution aiming measurements in deep inelastic scattering process at future Electron Ion Colliders. The result depends on conventional variables $x$ and $Q$ as well as on $τ_1$ and is relatively compact and easy to implement for numerical calculation. Three different choices of axis, with respect to which $τ_1$ is measured are considered in the Breit frame. The first is the one optimally adjusted to minimize $τ_1$ and the second and third are taken from anti-$k_T$ and Centauro jet algorithms defined with a jet radius parameter $R$, respectively. We find that the first and second give the same result at this order and are independent of $R$, while the third depends on the radius. This fixed-order result provides a nonsingular contribution to be combined with a singular log-resummed contribution to give the full spectrum in $τ_1$ space and also shows how fixed-order and resummation regions change as a function of $x$ and $Q$.
