Jay Hauser: Present Research Activities

Quick update in March 2014 - a lot has happened since this web page was last seriously updated. Who has time to make a nice web page?

Some recent highlights:

  • We got our CMS detector, including the CSC muon particle detection system, up and running smoothly and with high efficiency. Kudos to Greg and Misha for that!
  • We took a lot of 7 TeV and 8 TeV proton-proton collision data. The whole year 2010 was spent at 7 TeV, and 2011 and 2012 were years in which data was collected at ever-increasing rates.
  • We discovered the Higgs particle! That at least answered the first question on our "Physics Goals" list below.
  • We looked for heavy stable charged particles but didn't find them :( At least we got a publication out of that, and Chris got a PhD thesis.
  • We are very busy installing new CSC detectors and refurbished electronics in anticipation of a big data run with LHC at a higher energy for proton-proton collisions of 13 TeV and higher rate of collisions starting in 2015. David, Matthias, and Eric were instrumental in building the new CSC chambers, and Andrew did a lot of work on the electronics.
  • This year, I have been leading the preparation of a "Phase 2" upgrade Technical Proposal document on behalf of all the muon detectors of CMS.
Currently the biggest problem with my web pages is that there is no satisfactory combined web page for the research of the entire UCLA group doing research on CMS. Besides myself, this includes Professors Robert Cousins and David Saltzberg, plus a number of postdocs and graduate students. We work very closely and harmoniously as a group, and it's a shame we haven't highlighted that with a web page that is snazzy and comprehensive. Maybe some day...

Summary as of October 2009

I work on the Compact Muon Solenoid (CMS) experiment (see also this link to CMS) Compact Muon Solenoid (CMS) experiment at the CERN laboratory in Geneva, Switzerland, where the World Wide Web (or just "web") was invented. The CMS experiment looks for evidence of new particles or forces by studying high-energy collisions between proton beams in the Large Hadron Collider (LHC) accelerator. Currently I am spending most of my time in Geneva, serving as the Project Manager for the part of CMS known as the Cathode Strip Chamber (CSC) muon detector.

In the past, my group has built large numbers of electronics cards for triggering (selecting) muons with the CSC muon detector, and has done a tremendous amount of work to get this large and complex detector running smoothly. We have also made a specialty of refining the timing of the CSC detector.

Now as the data begins to accumulate and luminosities increase, we can start to turn our attention to searches for new particles and forces of nature. I work closely with UCLA professors Robert Cousins, David Saltzberg, and Cline, as well as their postdoctoral researchers working on the CMS experiment. A rather detailed picture of what my team was doing as of Oct. 2009 can be found here.
