The Core-Collapse Supernovae Particle Physics Interactions

Abstract

This study investigates the role of specific particle physics interactions in simulations of core collapse supernovae, with a focus on understanding how varying levels of inclusion impact the accuracy of gravitational wave predictions and results of simulations. Different research groups often approach these simulations with varying degrees of complexity, cutting corners by omitting certain reactions or simplifying others. This project systematically evaluates the implications of these choices, comparing the particle physics interactions included, the dimensionality of the simulations, and the governing equations used. Our goal is to identify how these factors influence the precision of numerical simulations. By providing a comprehensive analysis of the advantages and drawbacks of including different particle interactions, we aim to improve the development of simulations used by instruments like LIGO (Laser Interferometer Gravitational Wave Observatory)
