摘要

我们的 NXV4 非阿贝尔多态 C++ 软件包（通过 JINRlib 提供）适用于粒子物理跟踪和顶点应用，以及其他一般三维任务（螺旋计算、不变质量、自旋对齐等）。该版本包括 CPX（复数）、VEC（三维矢量）和 MTX（3 × 3 矩阵），均为多态。软件包中的多层实例化突出了我们的（i）"纸上笔 "范式，通过这种范式，我们使用户级 C++ 尽可能接近纸上计算；（ii）我们的 "F-77 for the user "理念。我们还展示了顶点化示例代码在 CPU 上的卓越性能。

NXV4 C++ Package for Particle Physics Flash Algorithms

Our NXV4 non-abelian polymorphic C++ package (available through JINRlib) is intended for particle physics tracking and vertexing applications, as well other general 3D tasks (helicity computations, invariant mass, spin alignment, etc). The distribution consists of CPX (complex numbers), VEC (3D vectors) and MTX (3 × 3 matrices), all polymorphic. Multiple-layer instantiation available in the package highlights our (i) “Pen-on-Paper” paradigm, through which we bring user-level C++ as close as possible to paper computations and (ii) our “F-77 for the user” philosophy. We also showcase the excellent CPU performance of our code for example cases of vertexing.

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.
