Yadism: Yet Another Deep-Inelastic Scattering Module

We present yadism, a library for the evaluation of both polarized andunpolarized deep-inelastic scattering (DIS) structure functions and crosssections up to N3LO in perturbative QCD. The package provides computations ofobservables in fixed-flavor and zero-mass variable flavor number schemes. Theimplementation of the general mass variable flavor number schemes is supportedthrough the high virtuality limits for the heavy flavor coefficients. Inaddition, yadism provides a set of tools for the generation of interpolationgrids in the PDF-independent PineAPPL format, allowing to test the PDFdependence on any DIS observable without needing to rerun the computation. Thiswork is part of an ongoing effort to standardize the format of theorypredictions in high-energy physics within the pineline framework. The code isopen source, written in Python and documented to facilitate usage,integrations, and further extensions. Finally, the code has been benchmarkedagainst the widely used APFEL++ and QCDNUM libraries.
