Introduction

This page is a work in progress and contains information to remind myself how to run things.

Running ATLAS jobs locally

Log into heplnx109.pp.rl.ac.uk and do kinit

source /gridsoft/SL5/atlas/software/15.6.6/setup.sh -tag=15.6.6,setup,32
export CMTPATH=${HOME}/testarea/15.6.6:${CMTPATH}
cd testarea/15.6.6/

The analysis

Local conditions access

MC Data

Real Data

To analyze real data you must set the following environment variables:

export FRONTIER_SERVER="(serverurl=http://lcgft-atlas.gridpp.rl.ac.uk:3128/frontierATLAS)"
export ATLAS_POOLCOND_PATH=/gridsoft/SL5/atlas/local/conditions/

Running on the grid

source setup.sh -tag=15.6.10,32,setup
source /afs/cern.ch/atlas/offline/external/GRID/DA/panda-client/latest/etc/panda/panda_setup.sh

Location of files

Local file for testing purposes

athenaCommonFlags.FilesInput = [ "/home/hep/dewhurst/data/mc09_valid.108407.Pythia_directJpsimu4mu4.merge.AOD.e347_s585_s582_r812_r814_tid096141/AOD.096141._000006.pool.root.1"]

There is a list of interesting physics runs which can be found here. You can find the runs you are looking for with the atlas run query tool. For the initial data taking period the B-Physics group is putting their Ntuples here.

Downloading files to RAL PPD

To download files directly to the dcache storage element at RAL do this:

source /afs/cern.ch/atlas/offline/external/GRID/ddm/DQ2Clients/setup.sh
export DQ2_LOCAL_SITE_ID=UKI-SOUTHGRID-RALPP_SCRATCHDISK
voms-proxy-init -voms atlas
dq2-get -S srm://heplnx204.pp.rl.ac.uk:8443/srm/managerv2?SFN=/pnfs/pp.rl.ac.uk/data/atlas/atlasralppdisk/dewhurst/ user.JamesCatmore.155697.f261_m496.muonstream_StandardGRL_prelim_muon_yellowPlus_7TeV-v02-pass1.staco/

Make sure you are not in the dcache element (ie do cd $HOME) otherwise you will get an error that you are in a read only file system.

Getting ROOT to work

To get root to work correctly do:

export LD_LIBRARY_PATH=/opt/d-cache/dcap/lib:/opt/d-cache/dcap/lib:/opt/d-cache/dcap/lib64:/opt/glite/lib:/opt/glite/lib64:/opt/globus/lib:/opt/lcg/lib:/opt/lcg/lib64:/opt/classads/lib64/:/opt/c-ares/lib:/opt/ppd/root/5.26.00/x86_64-slc5-gcc34-opt/root/lib/
export ROOTSYS=/opt/ppd/root/5.26.00/x86_64-slc5-gcc34-opt/root/
export PATH=/usr/kerberos/bin:/opt/d-cache/srm/bin:/opt/d-cache/dcap/bin:/opt/edg/bin:/opt/glite/bin:/opt/globus/bin:/opt/lcg/bin:/usr/local/bin:/bin:/usr/bin:/cern/pro/bin:${ROOTSYS}/bin:/usr/local/sbin:/sbin:/usr/sbin

Jpsi Information

All information is being stored on the sharepoint which can be found here. This information is likely to become rapidly out of date. There is a daily BPhys meeting at 3pm (UK time) via Evo. Plots of di-muon candidates can be found here.

Meetings of note:

• A list of all recent B-Physics meetings
• First J/psi event in the ID Tracking Resonance weekly meeting 13/4/10
• J/psi -> mumu/ee approval meeting 12/4/10
• Informal meeting on J/psi -> mumu 9/4/10

Bd J/psi K0* Analysis

The next section contains details on the status of the Bd -> J/psi K0* analysis.

Athena analaysis

The is done using the Bd2JpsiKstar code written by Adam Barton. The currently available ntuples not using the

Ntuple slimming

This is currently done using Pavel script. Julie has run this code which can be found on:

heplnx111.pp.rl.ac.uk
ls -lrth /scratch/jk67/DataAug2010_ntuples/
total 2.7G
-rw-r--r-- 1 jk67 atlas 7.6M Sep  7 13:26 DataAug2010_BdJpsiKstar_jpsiMassConstraint_periodB.root
-rw-r--r-- 1 jk67 atlas  11M Sep  7 13:27 DataAug2010_BdJpsiKstar_jpsiMassConstraint_periodC.root
-rw-r--r-- 1 jk67 atlas 500M Sep  7 13:54 DataAug2010_BdJpsiKstar_jpsiMassConstraint_periodD.root
-rw-r--r-- 1 jk67 atlas 1.6G Sep  7 14:57 DataAug2010_BdJpsiKstar_jpsiMassConstraint_periodE.root
-rw-r--r-- 1 jk67 atlas 586M Sep  8 09:04 DataAug2010_BdJpsiKstar_jpsiMassConstraint_periodF.root

Analysis code

Currently code is in:

/home/hep/dewhurst/BdJpsiK0star

To run it do:

.L BdJpsiKstar_analysis.cpp+
analysis("/scratch/jk67/DataAug2010_ntuples/", -99,"")

FTS script development

Aim is to right a script which plots the numbers that can be found on: http://lcgwww.gridpp.rl.ac.uk/cgi-bin/fts-mon/fts-mon-dev.pl
