QCDmodeller

QCDmodeller is an open-source software tool designed to facilitate the modeling and analysis of quantum chromodynamics (QCD) processes, particularly in the context of hadron spectroscopy and the study of exotic hadrons. Developed primarily for particle physicists and computational physicists, it provides a framework for simulating the interactions of quarks and gluons within quantum field theory. The software is built on the principles of lattice QCD, a method that discretizes spacetime to enable numerical simulations of QCD on high-performance computing systems.

QCDmodeller is particularly useful for investigating the properties of mesons, baryons, and other composite particles, including hypothetical states such as tetraquarks and pentaquarks. By employing advanced algorithms, it allows researchers to compute mass spectra, decay widths, and other observables, aiding in the interpretation of experimental data from facilities like the Large Hadron Collider (LHC) and other particle accelerators. The tool integrates with libraries such as QDP++ and Chroma, which provide essential functionalities for lattice gauge theory calculations.

The software is distributed under an open-source license, encouraging collaboration and modifications by the scientific community. It supports parallel computing, making it suitable for large-scale simulations that require significant computational resources. While primarily intended for academic research, QCDmodeller also serves as an educational resource for students studying advanced quantum field theory and computational physics. Its modular design allows users to extend its capabilities for specialized applications, though it requires a strong background in theoretical physics to operate effectively.
