Digital-Computer Analysis of Data from Bubble Chambers : Kinematic Analysis of Complete Events

Abstract

A digital computer program called KICK (K‐meson Interaction Coplanarization and Kinematics), which carries out the analysis of complete bubble chamber events, is described. The program inputs data from a single‐track analysis program which has used raw track measurements to perform the spatial reconstruction of tracks and has fitted appropriate curves to them. KICK consists of a set of general processing or analysis routines, each of which is capable of carrying out one of the unique processing steps to which a given event may have to be subjected for proper analysis, for example, ``Input Event,'' ``Fit Vertex,'' ``Transform Variables Along Track,'' ``Output Results,'' etc. Also included is a set of event‐type control subroutines each of which, calling upon the proper sequence of these general processing routines, is able to carry out the desired analysis of a particular type of event. This program is in use on IBM 704/9's at many laboratories.
