Hauser - Biographical Information

Hauser is the system manager for the muon system of the CMS experiment, and is spending the majority of his time this academic year working at the CERN laboratory near Geneva Switzerland. The CMS and ATLAS experiments co-discovered the Higgs particle in July 2012. The Large Hadron Collider accelerator and the CMS detector were upgraded in 2013 and 2014. The collision center-of-mass energy was increased from 8 to 13 trillion electron-volts, and the rate of proton-proton collisions was increased to more than a billion per second. CMS has been collecting data since early 2015, in order to understand the Higgs particle and the phenomenon of electroweak symmetry breaking better, and to look for evidence of Supersymmetry or other new physics beyond the standard model such as extra dimensions.

The CMS muon system consists of four detection technologies: Drift Tubes (DT), Cathode Strip Chambers (CSC), Resistive Plate Chambers (RPC), and Gaseous Electron Multiplier (GEM) and involves the work of 400 physicists from 62 institutions worldwide. Hauser is responsible for coordinating all of the activities necessary to keep the muon detectors working, and planning for upgrades needed for `Phase 2' of the LHC, where the proton-proton collision rate will be further increased to as much as seven billion per second.

UCLA has a large research effort in CMS, lead by Professors Robert Cousins, David Saltzberg, Michail Bachtis, and Professor Hauser.

More biographical information

Hauser grew up mostly in Ann Arbor, Michigan. Hobbies were amateur astronomy, photography, and trumpet playing. He speaks Chinese and cooks Chinese food reasonable well. Plays tennis often, skis and snowboards occasionally, and plays the trumpet and the piano. Married with several grown-up children.

Hauser received a B.S. degree in Physics and Astronomy from the University of Michigan in 1979, and received a PhD in 1985 from Caltech on the topic of charm particle decays based on electron-positron annihilation and the Mark-III detector. Then as Fermi Fellow at the University of Chicago, he built and commissioned the `Level 2 trigger' data selection system of the CDF experiment, and was briefly a Wilson Fellow at Fermilab.

Hauser came to UCLA as an Assistant Professor in 1990, and conducted physics analysis and served as the first convenor of the CDF Exotics physics group. Hauser also built part of the CDF electromagnetic calorimeter upgrade. Hauser became Full Professor in 1998.

Hauser analyses based on CDF data (1989-2008) include the first observation of charmed particles at a hadron collider, the first measurement of lepton charge asymmetry in W boson decays at a hadron collider, an early search for anomalous production of jets and missing-energy from Supersymmetry, a search for anomalous production of multi-leptons from Supersymmetry (R-parity conserving as well as violating cases), and a precision measurement of the top quark mass using the matrix element method.

Hauser worked on the CSC system of the CMS experiment since late 1994; he designed the CSC trigger algorithm, built some 1600 high-speed programmable electronics boards of various types, and commissioned the electronics in CMS. He was project manager for CSC from 2010-2015 before becoming system manager for the whole CMS muon system upon its managerial unification.
