Electron plots are made using W -> e nu events. "Current Release" Monte Carlo is 4.9.1 plus "winter 2003 ewk patches", such as the boson pt tuning and extra X0 material (wewk0e sample). The extra material is 4.5% X0 of Copper (0.064 cm) in the central and 33% X0 of Iron (0.59 cm) in the Plug detectors. This gives sufficient agreement (with some analysis level "tweaks") for the publication of the W,Z cross sections and ratios. "next release" is 5.3.0pre1 simulation, 200/pb of data collected till september 2003, 4.11.1 remake sample.
Boson Pt tuning and extra X0 material for central detector (copper) will be included in 5.x, so no patches should be needed to reproduce this level of agreement. Lshr should also be fixed in 5.x simulation.

Dijet Balance with R=0.4 Cone
Plot on the right is made with a tuned single-particle response curve shown as the magenta curve in the plug calorimeter. Pythia di-jet events are used for Monte Carlo. (plots from Charles Currat) |

ready to go | Lateral Shower Development in CEM Distributions for the fraction of energy leaking into the a given tower as a function of track position in the central tower, for a 3-tower window. Top row = left tower, middle row = central tower, bottom row = right tower. left column = phi direction, right column = eta direction. open circles = MC, filled circles = data (GJTC09) (plots from Pasha Murat, see simulation meeting talk for details) |

Lateral Shower Development in CHA Same as above but for CHA. Performed tuning of GFLASH parameters defining "radius" of the hadronic shower and determined the scale factor to be 1.74 +/- 0.17 (plots and tuning from Pasha Murat, see talk above from details) |
