Abstract

In this work, the triple differential cross section of the complete process of production with subsequent decay of the top quark is expanded on the inverse scale of new physics, taking into account the denominator with the width of the top quark, which depends on the constants of the SMEFT operators. A study was carried out of the influence of linear and quadratic terms of the expansion into the differential section depending on \(\hat {s}\).

SMEFT算子在单顶夸克产生过程中的线性和二次贡献

在这项工作中，考虑到顶夸克宽度的分母取决于SMEFT算子的常数，在新物理的逆尺度上扩展了顶夸克随后衰变的完整生产过程的三重微分截面。利用\(\hat {s}\)研究了线性项和二次项对微分截面展开的影响。

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.
