Generate large number of models and allow to map where certain signatures are relevant or not eg.

1. Tool to study power of dilepton signatures • Generate large number of models and allow to map where certain signatures are relevant or not eg. • Same flavor (SFDL)/ different flavor dileptons (DFDL) • Anything you can imagine, top, EW bosons • Primary goal: where are SFDL and DFDL relevant, powerful, less powerful,... • Constraints on models from eg. SFDL/DFDL ratio ... • Build tool that generates a ntuple, each entry being a model with relevant quantities • This is very preliminary, mostly I want to get feeling if this is useful work. 1 CSC susy 5 phone meeting- 07/04/23

2. Principle • Loop over a set of model, for eg. mSUGRA and determine for each model: σ(pp →SUSY)B(SUSY→”interesting final states”) • For each susy model loop determine all σ(pp→X~Y~) • Compute all B(X~ → e/µ/τ/top/W/Z...) • Compute σ(pp →SUSY)B(SUSY→eµ) = Σσ(X~Y~) x B(X~Y~ →eµ) 4) For the time being, some approximations to simplify combinatorics, accuracy ~5% Rely on Isajet 7.74 Sum over all possible SUSY primaries 2 CSC susy 5 phone meeting- 07/04/23

5. Inclusive SUSY Branching into 0, 1, 2 muons 5 CSC susy 5 phone meeting- 07/04/23

6. Inclusive SUSY Branching into 0, 1, 2 taus 6 CSC susy 5 phone meeting- 07/04/23

7. Inclusive SUSY branching into exactly 1 e + 1 µ 7 CSC susy 5 phone meeting- 07/04/23

8. Inclusive SUSY branchings B(ee) , B(µµ), B(e), B(µ) /B(eµ) ´8 CSC susy 5 phone meeting- 07/04/23

9. Inclusive SUSY branchings B(ee) , B(µµ), B(e), B(µ) /B(eµ) • Looks like σB(->eµ) is at least 3 times smaller • than same flavour (ee or µµ) • - Look into details why? • Is this also the case in other SUSY models? • Next steps: • - go to GMSB, AMSB... • - vary sgn(µ), A0, tan(β) • Could this be used to try to exclude mSugra for eg.? 9 CSC susy 5 phone meeting- 07/04/23

12. Top + Z production cross section ~20% of total Susy cross section To be understood! 12 CSC susy 5 phone meeting- 07/04/23

13. Plan/ Ideas -- Validation with know points / started. -- Look at Sigma x B(->t Z,tW,WZ) , b production, other? -- Generate ATLFAST, fullsim of some interesting points -- eg m0= 500GeV, m1/2=300 GeV with B(->tZ)~20% / in progress -- Study constraints on parameter space imposed by measurements of BR(SUSY->ll’) or BR(l)/BR(ll) .... -- Do the same with AMSB, GMSB, NUHM -- Look into extra dimension models? -- Can we find signatures that would exclude a model? 12 CSC susy 5 phone meeting- 07/04/23

14. Suggestions/ comments from Giacomo • Use prospino to derive cross sections • M1/2 range is too high in my plot • M0 should go up to 3000GeV (why) • Look into Z production, gives interesting Z+jets+ETmiss signature • In mSUGRA there should not be any difference between electrons and muons • Requiring emu: is a way to cleanly select 2 leptons coming from the opposite branches of the SUSY event?
