**Creighton Hogg**University of Wisconsin-Madison 1/18/05 EDDE and Exhume Comparisons**Edde distributions on are the left hand side, and Exhume on**the right throughout the talk.. The Xi distribution is much more narrow in Exhume and covers a smaller range.**For EDDE the pT of one of the protons is always less than 1,**but for Exhume it has a longer tail..**The difference in the shapes of the pT distributions is**perhaps more obvious when the pTs of the protons are plotted against each other.**The energy distribution for the Higgs is much broader in**EDDE, but this follows from the differences in the Xi distributions.**The pT distribution of the Higgs differers slightly between**the two generators, with the center and width of the peak being a little different.**It is important to note that in Exhume, the b-quarks are**much more central.**As can be seen here, Exhume has the b-quarks much more**central than EDDE with a larger number of events in which both b quarks are within an eta of 3.5.**Summary**• Xi distributions have very different shapes. In Exhume it covers a smaller range. • Higgs energy distribution is much broader in EDDE because of the difference in Xi. • Resulting b-quarks are much more central in Exhume than in EDDE.
