Hi Hal,

Looks good. I check the figures and read through the "Triggers" section (I didn't check the rates line by line, but the numbers are consistent with what I remember).

Hi Elliot,

I've finally gotten around to making the changes to the diagrams that you suggested. Sorry for the delay! The updated version of the Flowdown document and charts can be found in docdb 269.

Specific changes are detailed in the change log.

Cheers  -  Hal

Thanks Elliot!

I'll make these changes to the diagrams.

I'm not sure I got the full meaning of the jet trigger point though - the text is a bit garbled and I want to make sure I'm not mis-interpreting. Are you saying that gHTT is only used in b-tagging, or is it something else?

By-the-way, Sarah Demers is helping to update the Science Flowdown document. We're planning to incorporate *some* updated information from the Yellow Reports while still retaining the good connection between science goals and tech specs that exists in the TDRs.

Cheers  -  Hal

Hi Hal,

I skimmed the text focusing on trigger, and didn't notice anything. I didn't check all your numbers (e.g. the limits on Lambda_HHH /Lambda_HHH_SM)

For the flowdown diagrams...

-- Muon trigger uses rHTT

-- Jet trigger uses gHTT (this is a bit one b/c b-tagging is important for getting the jet triggers out of HLT)

That's it...

Yes - the latest version is what's in docdb now.  -  Hal

Okay, I'll try to review them today... latest version is in docdb?

Hi Elliot,

Yes - I'll be updating these. Please send me the charts that you think
should be adjusted and I'll fix them.

Thanks  -  Hal
