sci-physics The FastJet package provides a fast implementation of the longitudinally invariant kt longitudinally invariant inclusive Cambridge/Aachen and anti-kt jet finders and a uniform interface to external jet finders (notably SISCone) via a plugin mechanism. It also includes tools for calculating jet areas and performing background (pileup/UE) subtraction. Build all standard and C++ plugins Use sci-mathematics/cgal instead of bundled algorithms
