Origin of Mass and Higgs Searches We have been looking for answers for the origin of mass!! Higgs particle seems to be deeply involved in it but…
We haven’t seen it yet and could be just around the corner, so you can be the one
Have many thesis topics that needs immediate attention New and brilliant ideas for searches needed We are leading this effort in the DØ experiment and are playing a
significant role in developing new tools in ATLAS experiment Work with top physicists at top HEP laboratories on the top
priority issue

Recent Higgs Search Results in DØ
UTA result now!
UTA result in Jan. 2006!
1fb-1~3times the data now.
Better than anyone else! Will be published soon!

Grid Computing I have created and been leading a regional grid organization,
called DOSAR, Distributed Organization for Scientific and Academic Research This organization relies heavily on the only U.S. Regional Analysis
Center at for DØ at UTA We have been playing a leading role in shaping the grid
computing in the state and in the world We are playing a leading role in developing ATLAS distributed
data analyses!! We obtained significant support for this effort from the ATLAS
experiment We became one of the three ATLAS Tier2 computing centers
We have a large computing room already in place in the new building

Computing Room in the New Building
We are ready to continually play a major role in grid computing!!
Physics Department Colloquium Oct. 2005, J. Yu
Linear Collider Detector R&D Simulated data study of GEM Digital Hadron Calorimeter and
Algorithm development
Opportunity for making the difference for the future!!
We play a leadership role ILC on beam tests and in a detector collaboration
Physics Department Colloquium Oct. 2005, J. Yu
Conclusions: You are the ONE!!! Exciting opportunities
ATLAS Detector assembly, commissioning and Higgs search Bring in new ideas to make the difference Abundant Ph.D. thesis topics
– You might even be the one finding the Higgs particle Opportunity to do research in Switzerland
Novel Detector R&D for the future Tons of master thesis topics
We are looking for good friends and colleagues to work with us to achieve rich physics goals Come and talk to me at Rm-242A or send e-mail to me at [email protected]
