Research interests:

I am an experimental particle physicist. I am currently a member of an international collaboration called CDF (Collider Detector at Fermilab), which conducts an experiment at Fermi National Accelerator Laboratory (Fermilab for short) located in Batavia, Illinois, USA, some 30 miles west of Chicago.

The CDF experiment studies collisions of the proton and antiproton beams circulating in the Tevatron accelerator at Fermilab. By studying the particles produced in the collisions, we can learn a lot about the elementary particles and the fundamental interactions (forces) working between them.
In particular, I am interested in the physics of the bottom (b) quark, or B physics, which concerns the production and decay properties of the hadrons containing the b quark. The B hadrons hold a lot of promises of advancing our understanding about the weak interactions between the quarks. The B hadrons are expected to exhibit violation of particle-antiparticle symmetry in some of their decay modes. The CDF experiment has already seen a hint of this phenomenon, called CP-violation. The study of these phenomena might someday lead to the understanding of why our universe seems to be made up of matter but of no or little anti-matter.


Summer 2001 update: CDF has resumed its operation, and we are taking data.
You can be an armchair physicist by looking at live CDF events online.


Spring 2006, the triangle is determined most precisely ever, in particular the length of the right-hand side, thanks to a measurement of Delta-ms from the CDF experiment.
