Notes
Career Context
- Daniele contract ending May (06:52)
- renewal not offered
- academic, external searches
- vacation planned afterwards
- Funding constraints cited (09:22)
- supervisor not responsible
- no position opened
- outcome considered unlucky
- Gian Marco job search (10:22)
- confidence remains limited
- academic options under consideration
Normalisation Bug
- MadDM–RAPID mismatch identified (11:40)
- relativistic normalisation differs
- factors affect coefficients
- testing exposed physics issue
- Majorana scaling proposed (15:09)
- effective operators rescaled
- one formula retained
- no RAPIDD flag needed
- Double-counting risk checked (16:28)
- MadGraph factors retained
- operator scaling separately adjusted
- direct-electron case affected
- Relativistic mapping needs separation (24:52)
- C4 differs by factor four
- RAPIDD reads relativistic coefficients
- non-relativistic mapping required
Direct Detection
- Quark coupling coverage questioned (27:18)
- current model mentions top
- lighter quarks matters in direct detection
- need to check if they are properly considered
- Electron detection updates added (32:19)
- self-conjugate dark matter supported
- Majorana terms included
- UFO models updated
RAPIDD Integration
- Electron code moving into RAPIDD (33:13)
- nuclear and electron detection
- branch under development
- results compared with MadDM
- Direct detection centralisation supported (34:29)
- remove legacy MadDM code (eg. solar capture, not used)
- retain relativistic coefficients from MadDM, pass non-relativistic to RAPIDD
- calculate signals in RAPIDD
- Legacy solar capture removal proposed (34:29)
- previously unused functionality
- output fixed to zero
- cleaner MadDM version expected
- Further testing deferred (35:53)
- stronger implementation validation needed
- dedicated discussion next meeting
- slides optional for follow-up
Releases And Follow-Up
- MadDM 3.8 prioritised first (39:05)
- push version to master
- complete direct and indirect changes
- test before broader migration
- MadGraph 7 adaptation requested (37:49)
- adapt output commands:
- For relic+direct: output standalone_fortran […]
- For indirect: output madevent […]
- add the keywords “standalone_fortran” and “madevent”
- Indirect detection discussion postponed (40:43)
- Antiproton features implemented (42:03)
- upper-limit exclusion checks
- anti-deuterium event outputs
- Galactic Centre best fit
- flux plots generated
- different propagation methods included
