Jet Reconstruction

Jet reconstruction is a process used in particle physics to identify and analyze high-energy particle streams called jets, which are produced when particles like quarks or gluons are created during high-energy collisions, such as those in particle accelerators. When these particles move, they quickly fragment into a spray of smaller particles, forming a jet. Detectors capture the energy deposits from these particles, and algorithms group these signals to reconstruct the original jet's properties—like its direction and energy—helping scientists understand fundamental interactions and the behavior of matter at tiny scales.
