The Miller Lab at The University of Chicago


The Miller Lab explores the properties of fundamental particles at the highest energy proton-proton collisions ever produced in a lab at the Large Hadron Collider at CERN in Geneva, Switzerland using the novel instrumentation of the ATLAS Experiment, dedicated high-speed electronics and real-time data processing, and cutting-edge data analysis algorithms.


 

Triggering on Lorentz-boosted objects

Complex objects often slip past our data filtering systems (triggers). By constructing extremely fast, sophisticated electronics systems that specifically search for these complex structures in real-time, we can recover these otherwise lost objects. This is the gFEX boosted object trigger for Run 3 of the LHC.

Exploring the Standard Model in extreme conditions

The Standard Model offers detailed predictions of the interactions of quarks and gluons with massive gauge bosons. Tests of these predictions at the most extreme energies accessible in the lab shed more light on our current understanding of the theoretical tools and the theory itself, as well as aiding in the search for new physics.

 

Searching for milli-charged particles

Though over a quarter of the mass-energy of the universe is widely thought to be some kind of non-luminous dark matter (DM), all experiments to date have failed to directly detect it, much less measure its properties. The milliQan experiment offers a new approach to detecting new fractionally-charged matter that could constitute a component of the dark matter.
