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.

A. Sobol: CMSPostdoctoral Research Associate, to leave group imminently to resume position in Russia

Senior Research Associate, left group in January 2007 for Fermilab Computing Division

• 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.

HEP Group Education and Outreach

Summary of initiatives• The Cosmic Ray Observatory Project (CROP)

• $1.34 Million NSF grant• Snow serves as task leader for Education/Outreach

for the Pierre Auger Observatory in Argentina and Colorado

• Claes serves as Education/Outreach for the emerging DUSEL and UNO initiatives in Colorado

• Bloom and Dominguez have important outreach initiatives funded by their NSF Career grants

The UNL HEP group faculty members are leadersnationally known HEP education and outreach initiatives

The UNL group in the CMS Experiment

UNL joined the CMS experiment in 1994• Preparation of the Technical Proposal• Luminosity Measurement• Forward and Diffractive Physics simulations• CMS Ph.D. Thesis Award Program

Major new initiatives over the last 3 years:Forward Pixel Detector – U.S. based project A. Dominguez is coordinator of Forward Pixel moduletesting

Tier-2 Computing Center at UNL – very high visibilityOne of 7 in the United StatesK. Bloom is project manager for all US Tier-2 centers

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 int’l conference to present thesis results• Work concentrated Sept.-Dec. when nominated theses are critiqued and ranked by Committee• Secretary’s work extends throughout the year• Most of the Thesis Award recipients have continued on CMS as postdocs and are in leadership positions
