- The ATLAS Experiment at CERN.
Operating at the LHC, the highest-energy particle collider ever
constructed ATLAS is exploring the energy frontier of particle physics.
My research on ATLAS focuses on searching for
new particles that are long-lived, which are predicted in many extensions
to the standard model. Particles that decay
milimiters to tens of centimeters from their production point
are detected by the very precise ATLAS tracker. My students, postdocs
and I participated in the
first LHC publication of this kind of search,
interpreted in the context of supersymmetric models.
papers, we added data, expanded the search signature, and
improved the analysis. In the
paper, we applied our expertise to the search for
right-handed neutrinos, achieving 20 times more sensitive limits than the previous search. We are currently increasing the sensitivity further, by improving our techniques and using additional final states..
The sensitivity of these
background-free searches will grow linearly with the LHC luminosity,
which will grow almost 100-fold relative to the last published
analysis. This poses a great opportunity, as well as interesting
technical challenges as we expand the search parameter space.
- The Belle II Experiment at KEK.
Belle II builds on the success of the previous-generation experiments,
and Belle, which greatly improved
our understanding of heavy-flavor physics and CP violation, leading to
Nobel Prize in Physics. Belle II collects data from
electron-positron collisions produced by SuperKEKB, the world's
highest-luminosity collider. The 40-fold increase in the collected
data set and use of an improved detector help probe flavor-changing
new physics at mass scales much higher than those of LHC.
My group is involved in several areas at Belle II:
- Searches for long-lived particles in parameter-space regions not accessible to LHC, particularly those probing heavy flavor. In particular, we are following up experimentally on our phenomenological papers 1908.0971 and 2012.00438, and divising additional ideas to search for long-lived particles at Belle II.
- Developingd new methods that take advantage of
Belle II's high spatial resolution to perform studies that have never
been done before.
- Using modern machine-learning tools to improve a broad spectrum of measurements. We are currently applying this technique to understand the nature of the exotic hadron X(3872), which appears to be a quantum superposition of a quark-antiquark bound state and a meson-antimeson "molecule".
Although I am not a theorist, I frequently collaborate with theorists
on phenomenology papers. They are included in my list of publications
- Experiments where I previously conducted research:
- The BaBar Experiment at SLAC.
- The CLEO Experiment at Cornell
