A quantum algorithm for the n-gluon MHV scattering amplitude
Erik Bashore, Stefano Moretti, Timea Vitos
We propose a quantum algorithm for computing the n-gluon maximally helicity violating (MHV) tree-level scattering amplitude. We revisit a newly proposed method for unitarisation of…
Event generation with exponential scaling in multiplicity using AmpliCol
Rikkert Frederix, Timea Vitos
Efficient generation of LHC events is hindered by the rapidly rising cost of evaluating QCD matrix elements with increasing multiplicity. We build on a recently proposed two-step s…
FASTColor -- Full-color Amplitude Surrogate Toolkit for QCD
Javier Mariño Villadamigo, Rikkert Frederix, Tilman Plehn +2
High-multiplicity events remain a bottleneck for LHC simulations due to their computational cost. We present a ML-surrogate approach to accelerate matrix element reweighting from l…
Leading-colour-based unweighted event generation for multi-parton tree-level processes
Rikkert Frederix, Timea Vitos
In this work, we revisit unweighted event generation for multi-parton tree-level processes in massless QCD. We introduce a two-step approach, in which initially unweighted events a…
