1What you should know already
This is not a general introduction to cafe!
For that, see:
­ Reiner's tutorial in Vancouver (linked from the  CSG web page)
­ Slava's talk on caf_utils (also linked from the CSG page)
So, you should already know roughly:
­ what cafe is
­ cafe structure (processors)
­ setting up a config file
This tutorial goes through a basic  physics analysis using cafe.
2Aim
A working example of a physics analysis:
­ The standard cafe tools:
­ data quality
­ standard object selection
­ applying weights to Monte  Carlo
­ Developing a processor to do your own analysis.
There is generally more than one way to do all of this!
­ this is a  combination of the  standard tools and my analysis
­ consider it a  working example, not the definitive  guide
­ there  are other analysis examples out there (top_cafe, wzmuxsec).
There is a tutorial wiki page (under  the  CAF section)
3­ repository for additional knowledge / tips.Format
All the code is in a cvs package:

What you should know already - - What I'm going to cover   Data Analysis - - Monte Carlo Analysis   - Other stuff

This is not a general introduction to cafe! For that, see: - Reiner's tutorial in Vancouver (linked from the CSG web page) - Slava's talk on caf_utils (also linked from the CSG page)

So, you should already know roughly: - what cafe is - cafe structure (processors) - setting up a config file

This tutorial goes through a basic physics analysis using cafe.

iAm

A working example of a physics analysis: - The standard cafe tools: data quality - - standard object selection - applying weights to Monte Carlo - Developing a processor to do your own analysis.

There is generally more than one way to do all of this! - this is a combination of the standard tools and my analysis - consider it a working example, not the definitive guide - there are other analysis examples out there (top_cafe, wzmuxsec).

There is a tutorial wiki page (under the CAF section) - repository for additional knowledge / tips.

All the code is in a cvs package: _ _ - manchester cafe tutorial

These slides are intended as a reference - you'll probably learn most by playing with the code and configs! - for example, try: - run the analysis as it is - changing some cuts - add some plots to the example processor - run the analysis with another trigger.

Rest of this tutorial

- setting up a working directory - how to find data and MC - a basic cafe analysis: Inclusive Z->mumu cross section - data quality selection duplicate event removal - - trigger selection (data) - physics object selection - some further selection & analysis - applying reco scale factors (MC) - applying trigger efficiencies (MC) - other MC tools - submitting jobs - getting the luminosity other things out there -

To simplify this, I've made two setup scripts: - on the tutorial wiki page (under CAF) https://plone4.fnal.gov/P1/D0Wiki/caf/ManchesterCafeTutorial - these were up to date at the time of writing!

manchester cafe tutorial _ _

Contains: - these slides! (doc/tutorial.pdf & .odp) - example config files (config and config/common directories)   example processor (src/Ana.cpp & _ _tutoria a.hpp) - an manchester cafe l/An - example job submission commands (doc j _ .sh) / ob sub - some skimmed data & mc (skim/) - only~100 events each - example for the lumi calculation (doc/lumi.txt & runrange.list)

Note on setup_once: - this will (quickly) become obsolete as cafe evolves.

“Ho wot od anA anylsis”

Common tools developed to make analysis as simple as possible - but I'm afraid you'll have to do some work yourself...   - configuring the common tools - writing your final analysis processor

Approach I take: - different trigger versions, detector performance... - easiest way to handle this is to split your data set - develop config files for each trigger / period example is structured in a way to minimise duplication. -

Reminder.. these are my methods, not THE method...

How to find Data and MC

From the CSG web page: http://www-d0.fnal.gov/Run2Physics/cs/skimming/fixPass2p170903.html

Pass 2 and Pass 3 data – we need both! For data, we'll use two SAM definitions: CSG_ _ highpt_ ASS3_p17.09.03 CAF 2MU P CSG_CAF_2MUhighpt_PASS2_p17.09.01

For MC: http://d0-france.in2p3.fr/WORKING_GROUPS/MONTECARLO/Catalog/current/section_summary.php We'll use p17.09.06 production MC, request ID 33670. Make sure you use MCv3! Corresponding SAM definition: _ _ CSG CAF MCv3-33670

A Basic Cafe Analysis Part 1: Data

For testing, I've skimmed some data and MC. - stored in the tutorial package.

We will start with a basic config file, and build up from there. - The setup_once script links the config files to your area - If not, they are in manchester cafe tutorial/configs _ _

Start with tutorial_one.config - runs the Stat processor – keeps track of global weights. - run range selection - data quality selection - trigger selection muon selection - Run with: cafe tutorial_ fig one.con
