UNL High Energy Physics GroupOverview
For the duration of the 3-year base-funding proposal (June 2007 – June 2010), the UNL HEP group will be pursuing frontier physicsresearch through its collaboration in Fermilab’s DZERO and CERN’s CMS Experiments.
The anticipated breakdown of commitment, averaged over the group,for the 3 years isYear One (2007-2008): 50% CMS, 50% DZEROYear Two (2008-2009): 60% CMS, 40% DZEROYear Three (2009-2010): 75% CMS, 25% DZERO
The group also leads a nationally recognized education/outreachexperiment, CROP – the Cosmic Ray Observatory Project, that,along with other outreach efforts, makes it a leading groupin physics education/outreach at many levels.

• Replacing these two positions is crucial to the group’s 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.

An example of our physics involvement
• 2007 internal exercise: “Papers we want to write in 2008”.• Each physics group: Full (Monte Carlo) data analysis of selected processes, PRL-quality paper, collaboration review.
• Snow in Diffractive group: “Measurement of rapidity gap survival probability from single diffractive and double Pomeron exchange dijet events at 14 TeV”; Extension of previous work of Snow/Sobol in CMSSW framework.
• Similar efforts by other UNL group members.
• Meeting with CMS physics group conveners at FNAL in April.
