Researchers have developed Lantern, a novel physics-guided diffusion model designed to improve the simulation of calorimeter showers for the High-Luminosity LHC. Unlike previous methods, Lantern addresses the statistical nature of diffusion models by incorporating physics-aware auxiliary losses, including a voxel residual loss and a graph Laplacian loss, to ensure physical accuracy. The model utilizes a technique called GradBlend to effectively combine these physics-based objectives with the standard denoising objective, leading to improved performance on the CaloChallenge Dataset 2.
