Abstract
The most powerful means of exploring, nature at small length scales is through the use of particle colliders Colliders smash particles together at high energies, briefly producing new particles through quantum fluctuations, which then decay into complicated sprays of energy in surrounding detectors. Much in analogy with how thedetails of our cosmic history are imprinted in thecosmic microwave background, the detailed features of theinteractions of elementarv particles are imprinted into macroscopie correlations in the energy flow of the collisioiproducts. Understanding the underlying microscopic physics in collider experiments therefore relies on our abilitity to decode these complicated correlations in energy flow,In turn, the desire to understand how to compute collider observables from an underlving quantum field theory (QFT) description has been a driver of theoretical developments and insights into the structure of QFT itself.
In this talk l will present some recent highlights in the quest to better understand the strong nuclear force at collider experiments, drvien by recent theoretical developments in the understanding of a class of observables called "Energy Correlators". I will then apply these development lto explore a variety of interesting phenomena in Ouantum Chromodynamics, ranging from weighing the heaviest quark, to imaging the most perfect fluid.
