Recap (Just in case you missed it the first time) Z˚ boson Production  By using detectors we are able to observe and analyze the particles being produced through the proton proton collisions of the LHC. With this data we can determine whether or not bosons, such Z and W bosons, were created during the collisions. For Z bosons two of the outcomes that we have come to expect are electron and muon pairs.

Recap cont. (Monte Carlo) The left plot shows all of the transverse momentum for electrons from Z bosons. The right plot shows the invariant mass for all the electron pairs (Z boson mass).

Recap cont. (Initial data from the LHC) Using data already collected from the LHC we were able to plot the transverse momentum (left) for all of the electrons. The mass plot (right) shows the mass of Z˚ bosons that were detected.

What’s New (Data/Monte Carlo Invariant Mass Comparison) After normalizing the previous histogram to the amount of data (normalizing to an integrated luminosity of 16 nbˉ¹), I was able to plot both the Data and the Monte Carlo on the same plot in order to compare the results.

More Data from the LHC (Data/Monte Carlo Comparison) Once more data had become available, we were able to detect 21 Z bosons. From there we created another comparison of the data from the LHC and the Monte Carlo, however in this situation we also compare the transverse momentum along with the invariant mass. Our luminosity value for this comparison increased to 100 nbˉ¹.
