Dear all,
The July 31st version of the Higgs Snowmass committee draft (the one we discussed
in the couplings meeting this morning) is available on the twiki:
http://www.snowmass2013.org/tiki-index.php?page=The+Higgs+Boson
My notes from the meeting are below (these are not yet incorporated in the July 31st draft).
We will continue these discussions during the Friday and Saturday meetings.
Best,
Andrei, Sally, Heather, Jianming, Chris, Rick
Table 1-1. Make it clear that ttbar is ~3 sigma uncertainty range (as used by xsec group).
Include new physics where there is an indirect impact on couplings from additional decays that are either picked up in SM decay search or are not.
Add composite models and light dark matter decays to theory models
Quote SM BRinv from ZZ->vvvv
Merge LHC cross section tables from theory and LHC discussion sections (1-5 and 1-6)
Add Zgamma to Table 1-7 (update with Atlas bb)
Add to table 1-8. Accept. Eff. and S/B (range - one by counting - one by MVA/sensitivty-based)
Table 1-9. Add H --> mumu.
Table 1-10. Add standard description on what a 7-parameter fit means.
Add additional projections listed separately (additional channels not covered by CMS/Atlas experiments)
Table 1-11. ILC update needed from Tim B e-mail. Numbers from CLIC on Zgamma. Explain notation of "-" and remove NA. Make notation uniform. Remove Brexotic. Clarify TLEP on whether the SM BRinv is included (limit is comparable to SM rate).
Add polarization used for each machine - including ILC(-0.8,0.3) and TLEP(0,0).
Reference to facilities group section should be added to explain why the options in the table
are what they are.
Table 1-12. From separate gamma gamma facility or as add on to linear collider? Or does it matter?
Ask experts if Higgs --> mumu is missing from muon collider estimates.
Table 1-14. Add muon collider rates if they include ZH operation. Check on TLEP H-->gamma gamma numbers.
Does 3000/fb include 300/fb for LHC?
Table 1-15. Should be BR_BSM for LHC
Table 1-16. Needs to updated (e+e- are not the 7-parameter fit numbers). Remove extra stuff (like Binv? or gHHH and do a similar cleanup in 1-15).
Put H->AA->bb(bb) into deviation discussions.
Table 17. Time-line added for these combination stories? Or not. The current plan is a no-overlap combination.
Add global summary table to conclusions that bring in the table numbers from all sections.
