Week+of+November+19th,+2012

I arrived at Quarknet today at 3:45 and began work immediately. I listened to Jason and asked him about what was next on the schedule for working. Grace helped me by showing me how to do calculations and how to sort and cut in excel. Jason told me how to sort the excel files, and he told me that we also made another column, phi1+phi2. I made this file, and got the answers for every event recorded. After this we took the events 439-525 and copied them into a new excel file. We believe looking at the phi1+phi2 should be around 0, due to the fact that cosmic rays go in opposite directions and have the about the same masses and other information, so the numbers should cancel each other out. This is why the number should be around zero. This is our initial cut for our search for cosmic rays. This initial cut will be the least accurate, as some of the events will not be evidence for cosmic rays. We sorted our grouping of phi1+phi2 into mass. We found 4 reasonable events, 3 of which were above 40, while the 4th was at a little above 39.6. On second look at that event we noticed that when you look at the E1+E2, it does not show very reasonable data. Dr. L came into the lab and asked about the groups work and showed us a program similar to the CMS E-LAB program, which I have previously used. This image is of the original data set, with the addition of E1+E2. The events were organized by Mass at this time. This image is just a test image showing the addition of a column and all of the events displayed. This image is of the cut events 439-525. These events also have another column inserted the phi1+phi2. This image is the second cut on our data set. This graph shows the 4 events which we believe could be the evidence of a cosmic ray. These numbers are close to or above the mass of 40, which was the mass that most cosmic ray events began to appear on our graphs that we looked at in many eyes. 39.6364 is the number which we do not know is actually evidence of a cosmic ray. The mass of the number suggests that it might be a cosmic ray, but the phi1+phi2 number, which is -.376 suggests that it is not. The other numbers have a phi1+phi2 number around 0.

Once I finished this work, I went back to the many eyes project and looked over a few mistakes. I responded to the comments given to me by my fellow classmates, with what I think to be reasonable answers, and I added the final two images to the project, which had not been uploaded due to a wikispaces error.
