Goals
Make it straightforward for physicists to ask
physics questions – not spend large amounts of time
understanding (impenetrable) software tools
Build on the technical expertise at many
collaborating institutions: (to date ANL, U of
Chicago, Indiana U, U of Illinois, Michigan State
U, UTA, U of Wisconsin)
Have a few (determined) individuals pioneer
the way and bring in our colleagues

The Way Forward
Select some appropriate set of processes and use
them to acquire the skills as well as to develop the
tools to be applied to detector systems of our direct
concern (e.g. calibration of the Tile Calorimeter, or
understanding the jet energy scale in gory detail.)
Pick processes which have an early physics impact
and a long term future (e.g. di-jet mass distribution
which will lead into a high mass Higgs search.)
Ultimately take at least one physics process all the
way through to publication level.

Some Specific Tasks
To be successful we need to probe everything in the system :
•to be comfortable with the tools (software, databases, event store)
•to be comfortable with the analysis environment (e.g. root & root macros)
•to have some standard access scripts and analysis software to use as
templates
•to have someone to talk to when things don't work as expected
We also need to have some specific objectives (e.g.):
•reconstruct and analyze data from the combined testbeam
•run Athena simulation for some particular physics process, reconstruct and
store data at CERN, analyze results in ROOT locally
•Install and execute Athena development from a LOCAL computer system

Accomplishments
Ntuples from GRID (Amir Farbin, Rob Gardner)
JetCalib framework (Ambreesh)
Jet NtupleMaker framework (Tom LeCompte -in
progress)
Examples of running jobs on lxplus and at bnl
Simple root analysis example (Ambreesh/Jimmy)
Root macros (Amir, Martina, Kelby)
Physics accomplishments - mainly in the area of
SUSY, but we have some Z/g + Jet balancing
and di-gamma studies making headway

Plans for Rome and
Beyond
What we accomplish for Rome will depend
on the availability of reconstructed DC2
data
We have a long list of topics being studied. All are
important.
My guess is that by Rome we will have studies based on full
simulations for:
Jet Scale, Resolution and Et calibration; L2 trigger for jets;
SUSY S/B; Jet Multiplicity for several processes; Higgs
Searches; conversion finding
