FERMILAB Silicon Detector Workshop
Representatives of the PETRA operations group and the JADE, Mark-J, PLUTO and TASSO collaborations at DESY celebrate in the control room at the end of a successful electron-positron run at 17.5 GeV per beam. In about six weeks during November and December, each of the four experimental groups collected a luminosity of 17 000 inverse nanobarns, despite a four-hour energy-saving shutdown every working day.

Search for ZZ Resonances in the Final State of Leptons and Neutrinos in Proton-Proton Collisions at 13 Tev Yanchu Wang Charlottesville, VA
Search for ZZ Resonances in the Final State of Leptons and Neutrinos in Proton-Proton Collisions at 13 TeV Yanchu Wang Charlottesville, VA B.S., University of Science and Technology of China, 2013 A Thesis presented to the Graduate Faculty of the University of Virginia in Candidacy for the Degree of Doctor of Philosophy Department of Physics University of Virginia May, 2019 ACKNOWLEDGEMENT First and foremost, I would like to express my immerse gratitude to my advisor Prof. Bob Hirosky, for his continual guidance and support through- out the last 4 years for me. He guided me into the world of experimental particle physics and fascinated me with his physics insight and technical skills. I would also like to express my gratitude to Dr. Hengne Li, the former post-doctor in our group who now works as a professor at the South China Normal University. His dedication to research has always been an invaluable source of inspiration to me. Moreover, I appreciate the efforts from the members of my defense com- mittee, including Dr. Brad Cox, Dr. P.Q. Hung and Dr. Nitya Kallivayalil, for their time reviewing my research, providing precious comments for my thesis, and approving my dissertation. In addition, I am grateful to the physicists I worked with and learnt from during my 2 years’ stay at CERN, such as Tote Hughes and Andrew Whitbeck in the HCAL Phase I upgrading team, Mario Galanti and Josh Kunkle in the HCAL Operation team, Thomas Peiffer and Vieri Candelise in the B2G MC Production team, and many more amazing researchers in the collaboration. -
