phasespace: n-body phase space generation in Python
Albert Puig Navarro, Jonas Nathanael Eschle · The Journal of Open Source Software · 2019
Simulated particle decays are common in experimental particle physics.They are used to study a wide variety of aspects of a physics analysis, such as signal response, detector effects, and the efficiency of selection requirements, in a controlled manner.While it is possible to encode complex physics dynamics into these simulations at the cost of increased complexity and larger computer requirements, in many cases it is enough to generate these simulated samples as if only kinematic physics occurred, i.e., in an isotropic way.This type of generation, called "phase space generation", is very fast and offers simple and predictable patterns, making it an attractive first step in many physics analyses.
