Research Description

My research in experimental particle physics has recently been in heavy flavor physics, which includes both the bottom and the top quark. I am a member of the DØ collaboration at the Fermi National Accelerator Laboratory, which is located near Chicago Illinois. At DØ, I have studied properties of the B meson, and in particular Bs mixing, which involves a Bs meson oscillating into its anti-matter partner. I have also been active in studying various particles including the χ(3872), and the Ξb and Ωb baryons. Most recently I have been studying CP violation by studying the decays Bs → J/ψf0(980) and Bs → J/ψf2´(1525) and searching for exotic states such as the X(4140) and the Zb.

I am also a member of the ATLAS collaboration at the Large Hadron Collider (LHC) located near Geneva, Switzerland. The ATLAS detector has been collecting data since 2010 and has accumulated a large data set at the world's highest center of mass energy. The LHC is one of the best places to search for new physics beyond the Standard Model, so I have primarily been involved in studying Super Symmetry to search for super-symmetric partners to the currently known forms of matter. With the discovery of the Higgs Boson, the LHC has hopefully just started on its path of many more discoveries.
