        Agenda

        Actions

        • Move next meeting back 1 h.

        Frantisek

        • Create a PR to update the MadGraph 7 UI prompt, initially using blue, with an option to disable/configure the color.
        • Update MG5 references to MG7 in the interface as part of the UI changes.
        • Update and push the code-splitting PR toward merging as soon as possible.

        Daniele

        • Rerun the MadGraph7 performance and cross-section validation on a smaller subset of processes.
        • Investigate the observed MadGraph5 vs MadGraph7 cross-section discrepancies.
        • Investigate unexpected throughput results, including cases where CPU and GPU performance appear identical, using sequential rather than parallel runs.

        Olivier

        • Merge MadGraph5 v3.8.0 into MadGraph7.
        • Port the quarkonia/leptonium features to MadGraph7.

        Open points

        • Resolve the MLM/polarization issues with mixed expansions, where diagram identification and weight evaluation currently depend on each other.
