QCDMAPT_F: Fortran version of QCDMAPT package

Abstract
The QCDMAPT program package facilitates computations in the framework of dispersive approach to Quantum Chromodynamics. The QCDMAPT_F version of this package enables one to perform such computations with Fortran, whereas the previous version was developed for use with Maple system. The QCDMAPT_F package possesses the same basic features as its previous version. Namely, it embodies the calculated explicit expressions for relevant spectral functions up to the four–loop level and the subroutines...

Title of program: QCDMAPT F
Catalogue Id: AEGP_v2_0

Nature of problem
A central object of the dispersive (or "analytic") approach to Quantum Chromodynamics [2, 3] is the so-called spectral function, which can be calculated by making use of the strong running coupling. At the one-loop level the latter has a quite simple form and the relevant spectral function can easily be calculated. However, at the higher loop levels the strong running coupling has a rather cumbersome structure. Here, the explicit calculation of corresponding spectral functions represents a somew ...

## 问题本质
量子色动力学色散（或称“解析”）方法的核心研究对象为谱函数（spectral function），其可通过强跑动耦合（strong running coupling）计算得到。在单圈阶下，强跑动耦合形式较为简洁，相关谱函数的计算也较为简便；但在更高圈阶下，强跑动耦合的形式变得相当繁琐复杂。此时，对应谱函数的显式计算则存在一定的……
