UNL High Energy Physics Group Overview
For the duration of the 3-year base-funding
proposal (June 2007 June 2010), the UNL HEP
group will be pursuing frontier physics research
through its collaboration in Fermilabs DZERO and
CERNs CMS Experiments. The anticipated
breakdown of commitment, averaged over the
group, for the 3 years is Year One (2007-2008)
50 CMS, 50 DZERO Year Two (2008-2009) 60 CMS,
40 DZERO Year Three (2009-2010) 75 CMS, 25
DZERO The group also leads a nationally
recognized education/outreach experiment, CROP
the Cosmic Ray Observatory Project, that, along
with other outreach efforts, makes it a leading
group in physics education/outreach at many
levels.

UNL HEP Personnel and Their Project Affiliations

• Replacing these two positions is crucial to the
  groups
• strength in CMS
• Bellavance replacement is foreseen to transition
  DZERO
• to CMS over the course of proposed 3-year
  program
• Ideal candidate DZERO graduating Ph.D. aiming
  for
• LHC involvement. Several top candidates exist.

DZERO is a mature facility in data-taking and
physics publication mode, with data-taking
continuing until 2009 and analysis extending
through 2010 UNL involvements in Level-2 and -3
trigger electronics and software, track
reconstruction software, physics analysis (QCD,
Electroweak, Top Quark, Higgs Searches, and New
Phenomena), internal Editorial Boards,
luminosity measurement, data-taking shifts, other
service work, Speakers Bureau, Public Tour

The CMS Thesis Award Program

• Unique to CMS at CERN
• Initiated by G. Snow in 2000, served as
  Secretary
• of the 8-member Committee for 7 years
• Committee has dealt with 49 nominated theses
• in 7 years
• Recipients receive plaque and expenses to an
  intl
• conference to present thesis results
• Work concentrated Sept.-Dec. when nominated
  theses
• are critiqued and ranked by Committee
• Secretarys work extends throughout the year
• Most of the Thesis Award recipients have
  continued
• on CMS as postdocs and are in leadership
  positions
