Top++: A program for the calculation of the top-pair cross-section at hadron colliders

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present the program Top++ for the numerical evaluation of the total inclusive cross-section for producing top quark pairs at hadron colliders. The program calculates the cross-section in (a) fixed order approach with exact next-to-next-to leading order (NNLO) accuracy and (b) by including soft-gluon resummation for the hadronic cross-section in Mellin space with full next-to-next-to-leading logarithmic (NNLL) accuracy. The program offers the user significant flexibility through the large n...

摘要：本文介绍程序Top++，用于数值计算强子对撞机中顶夸克对产生的总包容性截面。本程序可通过两种方式计算截面：(a) 采用精确的次次领头阶（next-to-next-to leading order, NNLO）固定阶近似；(b) 在梅林（Mellin）空间中对强子截面引入软胶子重整化，实现完整的次次领头对数（next-to-next-to-leading logarithmic, NNLL）精度。本程序通过丰富的可调参数（原文截断于large n...）为用户提供了显著的操作灵活性。
