SM diboson, ZZ combination

About the content of the note:

- Introduction on cross-section, differential and aTGC (general, then ZZ case) (ALEX, NICOLAS)

- ZZ analyses

--- ATLAS and CMS 7 TeV analysis description and differences (NICOLAS)

--- Signal sample generator parameters

 

- ZZ combination:

--- Theoretical framework for anomalous couplings  (ALEX, JOSH)

--- Statistical method used for the combination (SENKA, STEVE)

--- Treatment of systematic uncertainties and agreements achieved  (SENKA, STEVE)

— Results (SENKA, STEVE)

- Conclusions (ALEX)

PUBLICATION

ATLAS: PUB-NOTE

CMS: PAS-NOTE

In a meeting between CMS and ATLAS management, physics coordinators and spokespersons, it was agreed that we publish the results at arxiv. We make a single document that is both CMS PAS and ATLAS conf-paper, with a review procedure on both sides. The approval procedure is not completely defined yet, there will be an ARC or ARCs with both CMS and ATLAS members. Once the document is approved we submit it to the arxiv.

 

 

ANALYSIS WORK:

DLL limits match. Feldman Cousins still to be done: 2% disagreement, one parameter 6% -> test with different seed and number of toys to verify if this a statistical issue.

Editor CMS: Senka

Editor ATLAS : Alex

 

AI: Jake to find out if we need an ed-board.

AI: AFS user login to Alex, SVN access

 

Next meeting Feb 20, 16h00

Agree to have a first draft of the note by then. Editors were assigned.
