hoppet v2 release note
Alexander Karlberg, Paolo Nason, Gavin Salam, Giulia Zanderighi, Frédéric Dreyer
TL;DR
The paper introduces new features in the hoppet v2 code for particle physics calculations, including higher-order QCD and QED evolution and a Python interface.
Contribution
The paper introduces N³LO QCD evolution, massless quark structure functions up to N³LO, and QED evolution at NNLO QCD accuracy in the hoppet v2 release.
Findings
Support for N³LO QCD evolution in the variable flavour number scheme was added.
A new Python interface and CMake build option were implemented.
Performance benchmarks were updated with optimizations for interpolating PDF tables.
