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.
