# QCDMAPT_F: Fortran version of QCDMAPT package

## Description

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 ...
