DATA - MC COMPARISON AT THE Z0 PEAK
Based on hadronic events: only qq~ MC sample required. Processing 97D and v. 6.11 btag package.
The comparison is done normalising the hadronic selected MC to the hadronic selected data.

Unsatisfactory agreement at preselection level (can be reasonably attributed to a bad description of hadron interactions in the HPC - most "electrons" at presel. level in qq~ events are in fact hadrons). The agreement is quite good at el.ident. level.
Plots of several variables after preselection are shown ( .ps file ); no major disagreements between data and MC.
