gleichLIBINT

gleichLIBINT is a software library designed for the numerical computation of loop integrals in quantum field theory. It focuses on providing efficient and accurate methods for evaluating these integrals, which are crucial for theoretical predictions in particle physics. The library aims to simplify the process of calculating Feynman diagrams, particularly those involving multiple loops, by automating complex integration procedures.

The core functionality of gleichLIBINT revolves around techniques for symbolic and numerical integration. It supports various methods for handling divergent integrals, such as dimensional regularization, and provides tools for their analytic continuation. The library is designed to be modular and extensible, allowing users to incorporate new methods or customize existing ones. It often leverages symbolic manipulation tools to simplify integrand expressions before numerical evaluation.

Applications of gleichLIBINT include precision calculations for scattering processes at particle colliders like the Large Hadron Collider, where high-accuracy predictions are essential for comparing theoretical models with experimental data. Researchers use it to study phenomena in quantum chromodynamics (QCD) and electroweak theory. The development of such libraries is vital for advancing the frontiers of theoretical physics by enabling more precise and comprehensive calculations.
