A spinor technique in symbolic Feynman diagram calculation mesons

The authors present a recursive diagrammatic method for evaluating tree-level Feynman diagrams involving multi-fermions which interact through gauge bosons (gluons or photons). Based on this method, a package called COMPUTE, which can generate and calculate all the possible Feynman diagrams for exclusive processes in perturbative QCD, has been developed (available in both Mathematics and Maple). As an example, a calculation of the nucleon Compton scattering amplitude is given.

The Nijmegen hyperon-nucleon potentials (open access)

The Nijmegen hyperon-nucleon potentials

The Nijmegen YN potential models are reviewed. Differences with the models constructed by the Juelich group are highlighted. A mini- review is given of the status of the scalar mesons and their relevance for the NN and YN interactions. Finally, the reactions {bar N}N {yields} {bar Y}Y are discussed.
