Today I arrived at Quarknet at around 4:00. Once I got into the lab, I began to read the logbooks of Alex and Jason, because they came on Wednesday October 17. After reading both of their logbook entries, I then proceeded to work on my images for the many eyes project. The images that I began taking on Monday, are all compiled here. The images are not in the order that they appear on the many eyes webpage. Once I finished uploading all of these images, I had to leave. It was around 5:00 PM. This image of py2 parent rest frame shows a long line of events occuring above the gev of 40 E sum parent rest frame. The almost continuous line shown at the top of the graph, starting at 40 E sum parent rest frame, is what is believed to be a cosmic ray. It is a straight line of events, all with a very high mass, and increasing as the data in entered.

This graph of pz sum parent rest frame, shows a majority of dots, which also have a high mass value, above 40 gev. Most cosmic rays have high mass and appear above 40 gev, as this graph shows. The line indicates that as the event continues in one direction, the mass of the events increases. This allows us to lead to the conclusion that there is a cosmic ray, due to the nature of cosmic rays, which have high masses and are always in a straight line. This line is similar to the line below, but not the same. The line shown below has a different Y-axis and more events on the lower end of the X-axis.

This image of the graph Y axis px sum parent rest frame, shows a jumble of events detected in the CMS all of which seem to be under 5 on the X axis M parent rest frame. Once the mess of events is filtered out, there is a clearly visible straight, almost continuous line shown. The information shown in the image gives us an idea of what a cosmic ray should look like. Although the mass of the events does not start to really increase until just after 60 parent rest frame, you can tell that the mass slowly does increase, if not by much, but just a noticeable amount starting at 40 M parent rest frame. This graph is also quite similar to the graph Y-axis pz sum parent rest frame X-axis E sum parent rest frame. The only major difference between this graph and pz sum parent rest frame and E sum parent rest frame are the location of the events on the Y-axis, and the amount of events below about 5 X-axis M parent rest frame.

This image of pt2 parent rest frame shows a large heap of events occurring at around -10 on the X-axis pz1 and rising straight up in an almost straight line. This line is fairly clear, if not a little bit muddled by the events surrounding the central line. This graph shows that at on the Y-axis pz2 parent rest frame the events start increasing in mass starting at 40. This is probably starting to sound very familiar, and that is because evidence for cosmic rays usually begins at this point.

This graph representing M2 parent rest frame and E2 parent rest frame shows a line of events with an increasing mass at around .1 Y-axis M2 parent rest frame. It extends from starting at about 1 E2 parent rest frame up to about 53 E2 parent rest frame. This graph shows the line with points under 40 E2 parent rest frame with masses under about 75, with the lowest mass above 40 E2 parent rest frame being 82.1, while the maximum mass shown on this graph is 106. This shows a cosmic ray because the mass is increasing while the line remains straight.

This graph representing M parent rest frame and pz1 shows a large grouping of events near the bottom of the graph all under 40 Y-axis M parent rest frame. These events are of course not as important as the grouping of events protruding from the events under 40 Y-axis M parent rest frame. These events shown emerging are what we believe to be a cosmic ray. The reasoning behind this accusation is because, as shown, the mass of the events on this graph increase greatly while all staying in generally the same area. This shows that a cosmic ray probably passed through the detector. This graph also shows an anomaly at around 90 Y-axis M parent rest frame. It shows a stray group of events being picked up in the detector which seem to make a short, somewhat straight line. I do not know what that is currently but I am interested in finding out what it is, because it also appears in the graph below, Y-axis E sum parent rest frame and X-axis pz sum.

This graph has a whole heap of information riddled inside it. First of all, there is a large quantity of events occurring below 40 Y-axis sum parent rest frame. These events suddenly come to a stop after this point. A few scattered points spread across the graph but none are very substantial. Second, this is a clear image of what may be cosmic ray. This graph shows a line emerging from the large grouping of events, which is most likely a cosmic ray. The events that are shown here have an increasing mass and are in a straight line. This line is quite a clear and is shown at at about 0 X-axis pz sum. This graph also shows the strange anomaly which I referenced above. As shown in this image which I believe is clearer than the image above, a line appears at about 90 Y-axis E sum parent rest frame. As I said earlier I do not know what this may be, but I would like to learn what it is.

This image representing the graph y-axis pz2 parent rest frame by x-axis betaz shows on the graph several distinct lines. Lines that I think do not pertain any important evidence to a cosmic ray are the line of events that appear at around 1 y-axis, and another appearing at the around the same y-axis plot line, but from the x-axis .4 to 1.0. The line of events I am most interested in is the line appearing at around 0.0 at the center of the detector. This line of events does not give absolute or definitive evidence of a cosmic ray due to the fact that the line is far too short and does not rise to be above the 40 GeV that is normally seen. It caught my eye because it of the mass of the line is increasing. The mass of the events is shown increasing, but I don't think that this graph properly shows the evidence of a cosmic ray.

This graph is a key piece of information. This graph shows the a clear verticle line of events, going far above 40 GeV. I believe this graph gives clear evidence on the subject of cosmic rays. It has a full line emerging from around 0.0 on the x-axis px sum parent rest frame and extends to 106 on the y-axis E sum parent rest frame. The mass of the line of events shown increases in each event starting with at 40 GeV the mass of 39.6, then the farthest recorded event.

This graph representing y-axis pt2 parent rest frame by x-axis M parent rest frame shows a line increasing. I believe that this graph shows a cosmic ray because of the nature of the line that is shown. The line shown has an increasing mass as it increases upon the y-axis. The line of events is continuous and the events above 40 GeV have a higher mass than previous events.
