Upgrade results approval: CMS proposal

• CMS Upgrade Management has decided to extend to “ALL” Upgrade results the approval process applied to CMS performance results– Pre-approval in the DPG meeting– Approval in a Friday Run Coordination meeting– Results are appended to the Weekly General Meeting

agenda the week after in case of last minutes comments– Approved results are posted in a public twiki managed

by the DPG: at this point they can be shown in conferences

Some remarks• What’s behind the (proposed) approval process:

– The results are posted in a stable form for a while before any step: about a couple of weeks long process

– The (pre-)approval events have to be advertized widely (hypernews)– Anyone in CMS should be allowed to express its opinion– The (public) official repository helps the speakers and the managers to define the

“official” results• Present Tracker performance results have always been approved using the CMS

rules and everybody seems to be happy about that • CMS upgrade managers may not be aware of the wide range of “upgrade results”

when they assume that “all” the results have to go through this process• The usual problem caused by a formal approval process is that the conference

talk is always “in a few days”• The usual problem caused by a lack of approval process is that it may happens

that wrong, misunderstood or controversial results are presented in a conference and that recovering could be a waste of time

A Tracker counter-proposal?• We are thinking about a counter-proposal to be made to the CMS

Upgrade manager to reduce the load– We have had many upgrade talks with results since a while and they

may not be aware of that– We produce results which would fit in Tracker-only papers: why not a

Tracker-only approval?– This proposal should not be too much different, eventually, from the

scrutiny of the slides of the talks.• The proposal

– A lighter, tracker-only, approval process– The definition of a list of results which require only the light approval– But if the phase 1 and phase 2 MB’s want to adopt the CMS rules in all

the cases it would be even simpler…

Approval processes• The CMS official one• The Tracker-only one:

– Any L3 (or more)-chaired meeting can host an approval session• Upgrade simulation, TK general, DPG, phase 1 or phase 2 general or working

meetings• But it has to be announced as an approval session via HN

– If the results to be approved are posted one week in advance they can be approved during the meeting

– If the results are posted too close to the meeting one week waiting time has to be granted to allow for comments. The chair of the meeting will take care of the follow up offline

– Once approved the results are posted in an official repository (twiki page).• There is no need to have this page public outside CMS

• No approval but documents posted in the official repository

Result categories• POG – tracking; b-tagging• upgraded detector performance results: TDR-like, based on CMSSW simulations• track multiplicity simulations: with CMSSW, with and without detector effects• expected dose simulation• relevant test-beam results• sensor design: motivations• descriptions, parameter tables, processes• sensors/chip characterization: electrical, with sources, irradiation• sensor/chip characterization: test beam• basic detector/sensor/chip (expected) performance from non-CMSSW simulations: TCAD, radiation

effect, hit efficiency, charge collection, data losses• upgrade detector performance results based on non-CMSSW simulations: thermal/mechanical

behaviour,…• non-CMSSW simulation validation with non-CMS data• tkLayout tool results • schedule & plans• pictures of set-ups• upgraded detector/module/chip layouts: drawings, concept

Summary

• We need feedback from the Tracker Upgrade MB’s (soon) before replying to the CMS management

• If agreed we have to start to prepare the official repository with the help of the working group conveners– Anastasia can help • if she does not receive (too many) conflicting inputs…
