Aim of the project
Allow MadGraph to specify decay chains of the type pp>(t>(W+>e+ve)b)(t~>(W->jj)b~).
Tools
Work
- MadGraph:
- Implementation of pruning of topologies to speed up process generation for many final state particles
- Example: pp>(t>(w+>jj)b)(t~>(w->l-vl~)b~): 16 min 15 s with decay chains, 2 h 33 min without decay chains
- Allow only specified decay chains. Give information on which resonances must be on-shell to MadEvent
- Allow more than 9 external particles
- MadEvent:
- Read on-shell resonance information to generate only correct diagrams
- Allow more than 9 external particles
The implementation in MadGraph and MadEvent is completed, but needs to be tested with "real" physics. Still to do is:
- Diagram drawing for more than 9 external particles
- Allowing more than 10 external particles in MadGraph
Physics results and papers writeup
To be decided
