        Project Updates

        • RAPIDD updated with direct detection fixes merged to main

          • Updated for MadGraph 3.8 compatibility

          • Tested direct and indirect detection examples

         

        • New nuclear form factors integrated into RAPIDD

          • Added GCN, Fitzpatrick, SN100PN form factors

          • GCN recommended default, others kept for legacy checks

         

        • Inelastic dark matter support added in RAPIDD

          • Delta parameter shifts minimum velocity

          • Integrated Large Magellanic Cloud halo model

         

        • Compatibility issues with MadGraph 3.8 models noted

          • Some spin zero and one models fail to download

          • Need to confirm repository URLs with Daniele/Olivier

        Technical Discussions

        • Old direct detection module to be discarded in favor of RAPIDD

          • Old code simpler but buggy, less flexible

          • RAPIDD offers more functionality and bug fixes

         

        • Standardized testing advocated for RAPIDD

          • Plans to use GitHub/Copilot for unit tests

          • Daniele to check MadGraph 7 compatibility in parallel

         

        • Relativistic to non-relativistic operator matching implemented in RAPIDD

          • Current focus on spin independent/dependent operators

          • Full operator matching planned post-release

         

        • Matrix element evaluation and Q=0 approximation discussed

          • Current method numerically validated but no theoretical proof

          • Alternative approach via MedGraph vertex coupling considered

        Planning and Next Steps

        • Target release: full MadGraph 3.8 compatibility with updated direct and indirect detection (01:07:00)

          • Mattia to update dwarf part in direct detection

          • Testing and bug fixes ongoing for compatibility

         

        • MadGraph 7 integration postponed, considered a longer-term effort

          • Potential major overhaul, not feasible within months

          • Focus remains on stable 3.8 release

         

        • Weekly or biweekly meetings planned to maintain momentum

          • Friday mornings preferred for future calls

        Collaboration and Communication

        • Mattia updating dwarf detection branch, next meeting on 8th

        • Coordination with Daniele on MadGraph compatibility and testing

        • Olivier contacted regarding Claude access for testing assistance
