A generator cell for LHC event GANs — •Niclas Eich, Martin Erdmann, and Benjamin Fischer — III. Physikalisches Institut A, RWTH Aachen University

We present a network for generative modelling of LHC events using Wasserstein generative adversarial networks (WGAN). We use Lorentz boosts, rotations, momentum and energy conservation to build a network cell generating a 2-body particle decay. We allow for modifications of the resulting four-vectors following a StyleGAN approach. We train the generator using the Lorentz Boost Network as a pre-stage of the critic's network. We present first evaluations of the generator quality using Drell-Yan processes.
