3. NSF reverse site visit, March 14, 2007 3 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 Fermilab’s DZERO and CERN’s 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.
