Today I arrived at Quarknet at 3:40, and was shortly after greeted by Dr. L, once I had entered into the lab. He began telling me about what our project will be, which is learning about and searching for Cosmic Rays. After he told me what I would be working on, I began finishing up my 5th Milestone, as I was waiting for John and Alex to arrive to the lab. Once John and Alex arrived, John explained to us what Cosmic Rays are and how they are found in the CMS detector. John explained to us the different angles of viewing the CMS detector and how the angle of the cosmic ray affects how the Muons will spread out. We later learned about Z particles and W particles. A Z particle must have positive and negative charges, and must go in two opposite directions. A W muon is an extremely fast, and small particle, like the nutrino that almost surpassed the speed of light. John showed up the "Copy of 1000 dimuon events.xlsx" which can be found on Johns logbook. Once we talked about that John was finished talking with us about particles and the CMS detector, because he did not want the others to fall so far behind Alex and I. After all of this I played with the 3D CMS detector, inputting a few muon particle data sets. I also reorganized my logbook so that it is now organized by week, excluding the first log post. Once I was finished I left at around 5:30.
