Physics Projects

Ground Rules for this Page

Projects listed here should always include the following:

  • Brief description
  • Starting date
  • Primary person responsible plus nominal supervisor in case of students
  • Link to "clean" copy of accomplishments and status
  • Link to "dirty" copy of status, i.e. the electronic logbook for collaborative development

Projects involving students

Projects involving Undergraduates

Intro to Comphep

Brief Description: Install Comphep on uaf and hepuser, document how to use it, and use it to calculate some standard model cross sections as described in detail at IntroComphep? .

Starting Date: June 2006 BruceThayre? supervised by HaifengPi? IntroComphep? IntroComphepElog

Generator Study of Higgs Decay to ZZ(*)

Brief Description
Study Higgs decays to ZZ(*) at generator level.

Starting Date: June 2006
RamiVanguri? supervised by JamesLetts?
HtoZZatGenLevel?
HtoZZatGenLevelElog

Search for bosophilic (fermiophobic) Higgs-like particles

Brief Description:
As an extension of the CDF observation of WZ in the tri-lepton final state, we want to search for WWW final states with all 3 W's decaying into lnu. An outline of this analysis might look as follows.

  • use Comphep or some other appropriate tool to understand the Xsection * BR as a function of mH.
  • use Pythia WH production to generate signal MC with full simulation.
  • Use the DBNTuple package to determine acceptance, and define an optimal signal region.
  • Analyze the data, write a paper.

Starting Date: November 2006
Ending Date: November 2006

Background Reading is available at BosophilicReadingList .
After initial reading, as documented on the BosophilicReadingList it seems that this isn't worth persuing.

Projects involving Ph.D. Graduate students

Introduction to the CMS Detector

Brief Description: Use cmssw to generate, simulate, digitize, and reconstruct electrons, muons, and pions in the CMS detector. These are all single particle gun simulations. Use the event display to get an initial understanding of the CMS detector, and then determine efficiency, and resolution curves, reproducing those in the physics TDR volume 1.

Search for H decaying into WW into lnu lnu

Brief Description: Develop a Matrix Element Fitter to fit the di-lepton plus MET sample in CDF for a Higgs to WW to lnu lnu signature at fixed Higgs mass. Then scan across the Higgs mass region from about 100GeV to 170GeV or so. Determine a 95% CL upper limit for the product of Xsection times branching fraction for H to WW. Interpret this in terms of standard model, fermiophobic model, and possibly derive a limit on the Wilson Coefficients for the kind of model suggested by ManoharWise in their recent paper, where they predict Xsection enhancements up to a factor 2-3, independent of higgs mass.
