末态喷流的变味数方案

Variable Flavor Number Scheme for Final State Jets

Andre H. Hoang, Piotr Pietrulewicz, Daniel Samitz

摘要:

我们讨论了一个适用于末态喷注的变味数方案,它可以考虑任意有限夸克质量对包含喷注观测量的影响。该计划是一个推广的VFNS计划的PDF应用到设置与额外的动力学尺度,并依赖于适当的重整化条件的矩阵元素的因式分解定理。我们说明了一般性质的例子的深度非弹性散射(DIS)的端点区域$x\rightarrow 1$和事件的形状在dijet限制,特别是阈值校正的计算,一致性条件和关系的质量奇异发现在固定顺序的大量计算。

英文摘要:

We discuss a variable flavor number scheme (VFNS) for final state jets which can account for the effects of arbitrary finite quark masses in inclusive jet observables. The scheme is a generalization of the VFNS scheme for PDFs applied to setups with additional dynamical scales and relies on appropriate renormalization conditions for the matrix elements in the factorization theorem. We illustrate general properties by means of the example of deep-inelastic scattering (DIS) in the endpoint region $x\rightarrow 1$ and event shapes in the dijet limit, in particular the calculations of threshold corrections, consistency conditions and relations to mass singularities found in fixed-order massive calculations.
