I am pleased to announce version 2.0.0 of MARLEY, the first official update to the code since November 2023. This major release implements an improved model of the charged-current cross section that is described in arXiv:2604.26801 [hep-ph]. The previous MARLEY output format has been entirely replaced by the HepMC3 event record. The representation of neutrino interactions within HepMC3 data structures follows the recommendations of version 1.0.0 of the NuHepMC standard.
Since my last news post, the MARLEY v1.2.0 implementation paper was published by Computer Physics Communications. The recommended citations to use for MARLEY have been updated accordingly.
I am pleased to announce that the first peer-reviewed journal article presenting the MARLEY treatment of charged-current scattering on was published this morning in Physical Review C.
After several years of existence as an uninviting landing page for MARLEY’s Doxygen-based API documentation, the marleygen.org website has now been completely revamped.
