PC-JeDi: Diffusion for Particle Cloud Generation in High Energy Physics

arXiv:2303.05376v2 Announce Type: replace-cross
Abstract: In this paper, we present a new method to efficiently generate jets in High Energy Physics called PC-JeDi. This method utilises score-based diffusion models in conjunction with transformers which are well suited to the task of generating jets as particle clouds due to their permutation equivariance. PC-JeDi achieves competitive performance with current state-of-the-art methods across several metrics that evaluate the quality of the generated jets. Although slower than other models, due to the large number …
