Manuscript Title: Nonperturbative evaluation of the few-body states for scalar chi-
square phi interaction. | ||

Authors: C. Savkli | ||

Program title: phi3 | ||

Catalogue identifier: ADNO_v1_0Distribution format: tar.gz | ||

Journal reference: Comput. Phys. Commun. 135(2001)312 | ||

Programming language: Fortran. | ||

Computer: Sun 19. | ||

Operating system: Unix. | ||

Keywords: Nonperturbative, Bound states, Feynman-Schwinger representation, Monte-Carlo, Numerical evaluation, Elementary particle physics, QCD. | ||

Classification: 11.5. | ||

Nature of problem:The program provided here evaluates the mass and distribution probabilities of the fully interacting n-body propagator (n<=3) for scalar chi-square phi interaction in 3+1 dimensions. The evaluation takes into account all self energy, vertex dressing, and exchange interaction contributions except those involving matter loops (the quenched approximation). | ||

Solution method:The Feynman-Schwinger representation approach is used to express the field theoretical Green's function in terms of a quantum mechanical path integral. The resultant expression is evaluated using a Monte-Carlo simulation. | ||

Restrictions:Only n = 1, 2, and 3 body propagators are considered. The extension to n >= 4 requires straightforward modifications in the program. | ||

Running time:About 1 day for the 1-body propagator with the self energy. |
