Abstract

To measure the characteristics of quark and gluon jets in hadron–hadron collisions, two samples of jets are used. Given the large statistics of jets at the LHC, the two-sample method requires taking into account the following corrections: (1) use of measured fractions of quark and gluon jets instead of the model ones, (2) amendment for the contribution of jets with an unidentified type, (3) taking into account the dependence of the distributions of quark and gluon jets on the conditions for jet sample selections. The paper presents an improved two-sample method that takes into account these corrections.

关于测量强子-强子对撞中夸克和胶子射流的特征

摘要为了测量强子-强子对撞中夸克和胶子射流的特性，使用了两个射流样本。鉴于大型强子对撞机的喷流统计量很大，双样本方法需要考虑以下修正：（1）使用测量到的夸克和胶子喷流的分数而不是模型分数；（2）修正类型不明的喷流的贡献；（3）考虑夸克和胶子喷流的分布对喷流样本选择条件的依赖。本文提出了一种考虑到这些修正的改进型双样本方法。

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
