2. Overall Data Strategy – ESD’s
The physics drives the data strategy

3. Hidden Valley
The tunneling/mixing has an almost arbitrary time constant
SM Particles can appear anywhere in the detector

4. Hidden Valley
Detector and algorithms are optimized to find displaced vertices in the very center of the ID
Not here…
Many of our signals look like noise or badly formed jets or muons and are discarded by the default object ID algorithms in ATLAS
We require the complete ESD for all of our events.
(You’ll see many of these algorithms described later)

5. The Samples

6. ESD Data 2010: Skimmed ESD’s from the data
2011: DESD is only possibility
10 DESD’s in ATLAS
DESD’s are designed for background
1 of 10 is signal, and we are part of that
RPVLL – managed jointly by the SUSY group and the Exotics group
Our DESD is configured to write full ESD as the DESD
Full trigger rate
Will work on reducing size and rate as we better understand the analysis
Trigger is a stronger constraint, however.

Monte Carlo
Close to 50 samples for all the backgrounds and possible HV signals
This is about 20 TB of ESDs
We are responsible for saving this
Currently using Exotics group space for this
May soon have to find other places
Still adding more data samples to the list

8. Tools And Docs

9. Standard TTree Production
Everyone uses a standard TTree for actual analysis.
Code is in Exotics Group SVN:
Analysis/LongLived/HVHeavyFermionPairs
Everyone uses a standard TTree for actual analysis*.
Small little tool that makes plots of every leaf for x-checks

10. Documentation
Provides a general reference to all the common work, including
Triggers
Data Sets
TTree Versions and Source Code and location
Description of the contents of the TTree.
Background selection and elimination (like Line of Fire).

11. Outstanding Issues Still adding variables to the TTree
Complete re-run of MC samples takes less than a week
Private versions of TTree exist as people try new variables out
Learning how to use common PAT tools and utilities
Luminosity and GRL calculation
Changes in trigger list generate constant work downstream

12. Conclusion Data production and management is in hand
Small outstanding issues
Adding new variables
Re-production takes less than a week
Common leap off point for rest of analysis
Future
At some point will move to experiment standard D3PD’s – perhaps for winter conferences
Work on moving more analysis into AOD’s and reducing dependence on ESD format
