The milliQan Experiment: Search for milli-charged Particles at the LHC

Recently, a search for milli-charged particles produced at the LHC has been proposed. The experiment, named milliQan, is expected to obtain sensitivity to charges of $10^{- 1} - 10^{-3}e$ for masses in the 0.1 - 100 GeV range. The detector is composed of 3 stacks of 80 cm long plastic scintillator arrays read out by PMTs. It will be installed in an existing tunnel 33 m from the CMS interaction point at the LHC, with 17 m of rock shielding to suppress beam backgrounds. In the fall of 2017 a 1% scale "demonstrator" of the proposed detector was installed at the planned site in order to study the feasibility of the experiment, focusing on understanding various background sources such as radioactivity of materials, PMT dark current, cosmic rays, and beam induced backgrounds. The data from the demonstrator provides a unique opportunity to understand the backgrounds and to optimize the design of the full detector.Comment: proceeding for ICHEP 2018 SEOUL, International Conference on High Energy Physics, 4-11 July 2018, SEOUL, KORE

Glauber and Kawasaki Dynamics for Determinantal Point Processes in Discrete Spaces

We construct the equilibrium Glauber and Kawasaki dynamics on discrete spaces which leave invariant certain determinantal point processes. We will construct Fellerian Markov processes with specified core for the generators. Further, we discuss the ergodicity of the processes

Limit theorems for open quantum random walks

We consider the limit distributions of open quantum random walks on one-dimensional lattice space. We introduce a dual process to the original quantum walk process, which is quite similar to the relation of Schr\"odinger-Heisenberg representation in quantum mechanics. By this, we can compute the distribution of the open quantum random walks concretely for many examples and thereby we can also obtain the limit distributions of them. In particular, it is possible to get rid of the initial state when we consider the evolution of the walk, it appears only in the last step of the computation

Inseparable

Even though none of my relatives that I know of were killed or tortured by the Japanese, I am still afraid. I am afraid that my vicarious wounds still linger inside me, affecting everything I do. Jae Y. Yoo is a freshman at James Madison University. She is majoring in Computer Science and Minoring in Art, and wrote this essay in the Fall 2000 Sememster in GWRIT 102D. Writing this essay was a very personal and emotional experience to me. I owe so much to my dedicated classmates and extraordinary instructor Ms. Storey, who encouraged and inspired me to write what my heart feels. We touched and changed each other\u27s life, and gave each other little pieces of our own life. It was such a moving experience I have never felt before. I thank everyone for everything
