EKO: evolution kernel operators
Alessandro Candido, Felix Hekhorn, Giacomo Magni
Abstract
Abstract We present a new QCD evolution library for unpolarized parton distribution functions: . The program solves DGLAP equations up to next-to-next-to-leading order. The unique feature of is the computation of solution operators, which are independent of the boundary condition, can be stored and quickly applied to evolve several initial PDFs. The approach combines the power of N -space solutions with the flexibility of a x -space delivery, that allows for an easy interface with existing codes. The code is fully open source and written in Python, with a modular structure in order to facilitate usage, readability and possible extensions. We provide a set of benchmarks with similar available tools, finding good agreement.
