=FINAL PROJECT= Z events with ee/uu

This is a picture that we have from these events above. This is of the Z particle muons. By using formulas to find the frequency at which the events occur in each bin, I can see obvious peaks around 90 GeV, and then the 3 and 10 Gev for the j/psi and upsilon. This is very exciting to see because we can now use our knowledge of setting up equations in excel and the data to make our own histograms. The next picture shows the same data, but with a gaussian fit on the area that we wanted to see (90 GeV). We also have the electrons from the Z particle, but they are saved on the computer at Quark Net, and so it will be put on tomorrow. We are going to then be looking at the differences between the data, which will be very interesting.



Here is the picture of the data we collected last week of the electrons. What I noticed right away about the two different graphs were the amount of events in each bin. Therefore, we can really see how there are jagged peaks in the muon graph, while with the electrons, it is much smoother. The muons show how there were clearer hits as to how the mass was measured, while the electrons were more "all over the place."

Here are the two graphs, electrons then muons, that have the fits on the curves:
