Yadism: yet another deep-inelastic scattering module

Abstract

AbstractWe present , a library for the evaluation of both polarized and unpolarized deep-inelastic scattering (DIS) structure functions and cross sections up to N$$^{3}$$ 3 LO in perturbative QCD. The package provides computations of observables in fixed-flavor and zero-mass variable flavor number schemes. The implementation of the general mass variable flavor number schemes is supported through the high virtuality limits for the heavy flavor coefficients. In addition, provides a set of tools for the generation of interpolation grids in the PDF-independent format, allowing to test the PDF dependence on any DIS observable without needing to rerun the computation. This work is part of an ongoing effort to standardize the format of theory predictions in high-energy physics within the framework. The code is open source, written in and documented to facilitate usage, integrations, and further extensions. Finally, the code has been benchmarked against the widely used and libraries.
