Single Top Physics
Search for Single Top Quark Production at DØ
I have won the 2005 Tollestrup award for my postdoc work on single top at DØ!
A video of the award ceremony, including the talk I gave can be found
here.

Between September 2003 and July 2005 I was the co-convener of the Single Top
working group at DØ.
We have completed a search for single top quark production in the s-channel
and t-channel using 230pb-1 of data collected with the DØ
detector at the Fermilab Tevatron. We have set upper limits on the production cross
section that are a factor two better than any previous limits.
Our result is documented on the
single top public result web page
and has been published in Physics Letters B. We are
also working on a longer, more detailed article to be published in Phys. Rev. D,
which will contain both this neural network result and a cut-based result.
Single Top Phenomenology at Next-To-Leading Order
I am collaborating with Michigan State theorists C.-P. Yuan and Qing-Hong Cao
as well as with fellow experimentalists Chip Brock and Jorge Benitez on studies of single top quark production
at next-to-leading order in QCD. We have published a paper on
s-channel phenomenology
and a paper on
t-channel phenomenology at the Tevatron.
