Differentiable programming opens exciting new avenues in particle physics, also affecting future event generators. These new techniques boost the performance of current and planned MadGraph implementations. Combining phase-space mappings with a set of very small learnable flow elements, MadNIS-Lite, can improve the sampling efficiency while being physically interpretable. This defines a third...
We attempt to extend the typical stratification of parameter space used during Monte Carlo simulations by considering regions of arbitrary shape. Such regions are defined by directly using their importance for the simulation, for example, a likelihood or scattering amplitude. In particular, we consider the possibility that the parameter space may be high dimensional and the simulation costly...
Background estimation is already a bottleneck in several analyses at LHCb, and with the upcoming larger datasets, the demand for efficient background simulation will continue to grow. While there are existing tools that can provide quick, rough estimates of background reconstructed distributions (e.g. RapidSim), these cannot account for the effects of common selection criteria. The tool...
In many real-world scenarios, data is hybrid — i.e. described by both continuous and discrete features. At high-energy accelerators like the LHC, jet constituents exhibit discrete properties such as electric charge or particle-id. In this talk, we introduce a novel generative model for discrete features based on continuous-time Markov jump processes. By combining our approach with well-known...
AI generative models, such as generative adversarial networks (GANs), have been widely used and studied as efficient alternatives to traditional scientific simulations like Geant4. Diffusion models, which have demonstrated great capability in generating high-quality text-to-image translations in industry, have yet to be applied in the high-energy heavy-ion physics.
In this talk, we present...
