Z Boson

We took the data of the events and worked out the momentum of the two particles in all 3 dimensions. Then using this calculated momentum we found the value of the missing momentum by conservation of momentum that represents the neutral particle that was produced in the event. Then after taking the sum of the magnitudes of all of these momenta we calculated the Total energy of the event which is equivalent to the mass of the Z Boson when units are changed because of E=mc^2. Then we created a Histogram of the data allowing us to see the distribution of the data more clearly. The 89.7 to 93.7 range stands out more than the "background noise". I added a trend line to the histogram showing the average slope of the data. Our calculated mass based on the histogram is 89.7 and the error from the accepted value is 1.6%.
