Rivet中探测器效应的快速模拟
Fast simulation of detector effects in Rivet
摘要：
我们描述了铆钉MC事件分析系统中的检测器偏置仿真的设计和实现。使用C++效率和运动学涂抹函子实现，它允许在分析例程中指定检测器效果，根据分析的精确相空间和重建工作点进行定制。文中还给出了ATLAS和CMS实验中两个物理目标的一套标准探测器函数。最后，由于射流子结构是一类重要的物理观测通常被认为需要一个明确的检测器模拟，我们证明了涂抹的方法，调整到现有的子结构数据和铆钉实施，可以准确地再现射流结构的偏差ATLAS观察。
英文摘要：
We describe the design and implementation of detector-bias emulation in the Rivet MC event analysis system. Implemented using C++ efficiency and kinematic smearing functors, it allows detector effects to be specified within an analysis routine, customised to the exact phase-space and reconstruction working points of the analysis. A set of standard detector functions for the physics objects of Runs 1 and 2 of the ATLAS and CMS experiments is also provided. Finally, as jet substructure is an important class of physics observable usually considered to require an explicit detector simulation, we demonstrate that a smearing approach, tuned to available substructure data and implemented in Rivet, can accurately reproduce jet-structure biases observed by ATLAS.
