This simple analysis example is set up at Research level, i.e. it requires university-student-level programming experience.
Minimal acquaintance with Linux and the ROOT analysis package (https://root.cern.ch/) as well as a basic text editor is needed.
You should get an output file Mu.root, which contains histograms for 10000 input events (a small subset of the data).
These can be looked at using a ROOT Browser (see above, under Description). The most interesting histogram is GM_mass_log.
In order to compare it with the invariant-mass spectrum of di-muons in MUO-10-004, it should be viewed with the logy option. Of course with 10000 events
the comparison is poor, but the J/ψ (at log10(mass)=0.5), Υ (at log10(mass=0.98))
and Z (at log10(mass)=1.95, one event only) peaks should be visible.
Finally, to run over more or even the full data, edit the relevant parts of
the Python file demoanalyzer_cfg.py (see comments therein) and rerun.
Add up the output histograms from different (non-overlapping) input index files using ROOT tools.
<p>Use this with 2010 Mu primary datasets or any other 2010 primary datasets containing muons (see detailed instructions in code). You can also run this analysis on 2011 data, but please be aware that that the code has not been optimised for these data.
