# A new version of the multi-dimensional integration and event generation package BASES/SPRING

## Description

Abstract The Monte Carlo integration and event generation package BASES/SPRING V1.0 S. Kawabata, Comput. Phys. Commun. 41 (1986) 127, has been upgraded so as to generate events with 50 independent variables, and to integrate functions with an alternating sign. Its ability to integrate real functions with indefinite sign is found to be useful in the numerical evaluation of interference effects among various amplitudes. Besides these changes, its program structure has been completely reformed. Title of program: BASES/SPRING V5.1 Catalogue Id: AAFW_v2_0 [ADBJ] Nature of problem The previous version of the numerical integration and event generation package BASES/SPRING has been useful to obtain total cross sections and to generate events of elementary processes in high energy physics. It is applicable to processes with up to ten independent variables. In order to study, for example, e+e- physics at much higher energies, we often need more than ten independent variables to describe processes of our interest. As far as the numerical integration by BASES is concerned, it i ...
