Kenneth Bloom, Professor
Department of Physics and Astronomy
University of Nebraska-Lincoln
Lincoln, Nebraska, United States

Research:
Experimental high-energy particle physics focused on the top quark and its weak interactions.

Projects:
o The D0 experiment at the Fermi National Accelerator Laboratory (FNAL) in Batavia, Illinois, United States; http://www-d0.fnal.gov/.
o The CMS experiment at CERN in Geneva, Switzerland; http://cms.cern.ch/.
At UNL, I collaborate on these projects with faculty members Dan Claes, Aaron Dominguez, and Greg Snow.

I've also worked on:

o The CDF experiment, also at FNAL (1989-1992 and 1997-2004); http://www-cdf.fnal.gov/. My final project there was a measurement of the branching fraction for the (highly favored) final state Wb. We published a paper on this in Physical Review Letters. I served as convenor of the lepton-plus-jets subgroup of the top-physics group for a year and a half, and as the leader of the muon-software project for two and a half years. Years earlier, as an undergraduate, I wrote a senior thesis on data taken in 1988-89, a measurement of the cross section for Drell-Yan production of electron pairs with small invariant mass.
o The CLEO experiment at Cornell's Laboratory for Elementary-Particle Physics (1992-1997); http://www.lns.cornell.edu/public/CLEO/. My PhD thesis was on a complete characterization of the decay B->Dlnu using new neutrino-reconstruction techniques.
