The STAR experiment

Using a series of response functions generated from single particle geant simulations and integrating the jet finder algorithm, I took each pythia jet and found it's detector energy.

Progress report on a port of STAR offline software to Mac OS X. Analysis chains using StMuDSTMaker are running fine; full bfc chains and simulations abort when I try to gexec the geometry. I’ve attached unified diffs of my Mac-related patches for each top-level directory in case we want to incorporate them into the STAR CVS repository.

In attachment are components for Mechanical Test setup and connectivity test features.

These plots were made from the same set of 5000 single-gamma events that I have been using all along, as well as 5000 single-piminus and single-muon events with the same characteristics.  Note th

Using 5000 neutrons generated in GEANT, pointed at tower 481, I examined the actual energy and reconstructed energy in that tower for a range of neutron energies.

These plots were made from the same set of 5000 single-gamma events as before.  Clusters are 2x2 patches found by looking for towers with E>1, constructing the 2x2 patch containing the seed

I generated a pythia sample with 300k events in each of 8 pt bins: 7-9, 9-11, 11-15, 15-25, 25-35, 35-45, 45-55, 55+.

Each set of plots were made from 5000 events, with a flat pt distribution between 5 and 40 and a flat eta distribution between -.2 and 1.2.  Clustering was done by finding seed towers (towers wit
