Revision as of 09:54, 2 September 2011
In the following the GlueX Monte Carlo and and analysis code revision 8233 as of end of August 2011 is used. 50000 b1pi events are generated for two geometries. One is the current standard geometry with a model of the BCAL readout including a copper cooling plate. A second geometry is identical with the exception that the BCAL readout part has been removed. This was done to see the impact of the BCAL readout on the reconstruction of these events. The event vertex is randomly distributed within the 30cm long target along the z-axis.
The pi0 mass (left=standard geometry, right=no Bcal readout):
Here and in the following the black histograms are the thrown Monte Carlo values however the photon energies and charged particle momenta are smeared before the masses are reconstructed.
The omega mass (left=standard geometry, right=no Bcal readout):
The b1 mass (left=standard geometry, right=no Bcal readout):
The X mass (left=standard geometry, right=no Bcal readout):
