Multiple observations of phenomena which cannot be explained in the Standard Model suggest that we need new physics beyond what we already know. The proliferation of theories in the last decades and the absence of direct observation of new phenomena at the LHC suggests to develop analysis strategies as model-independent as possible, yet suitable to be applied in experimental searches at...
The Fermionic Portal Vector Dark Matter (FPVDM) framework generically predicts six-fermion final states arising from pair production of heavy vector-like fermions followed by dark-sector cascade decays. In the top-portal realisation (TPVDM), this structure leads to a distinctive and essentially background-free six-top final state, which persists across almost the entire parameter space...
Fast and precise evaluations of scattering amplitudes even in the case of precision calcu-
lations is essential for event generation tools at the HL-LHC. We explore the scaling behav-
ior of the achievable precision of neural networks in this regression problem for multiple
architectures, including a Lorentz symmetry aware multilayer perceptron and the L-GATr
architecture. L-GATr is...
