A recent study led by Charles Joseph Naim, published in Physical Review Letters, establishes a significant connection between 'entanglement entropy' at the formation of jets and the distribution of particles that emerge from them.

Utilizing data from the ATLAS experiment at CERN's Large Hadron Collider, the research analyzed jet particles resulting from proton-proton collisions, where quarks and gluons scatter to form new particles known as hadrons.

The analysis revealed that the distribution of jet hadrons aligned with predictions based on maximal entanglement, providing fresh insights into the fragmentation process.

Previous research indicated that greater entanglement among quarks and gluons leads to more complex particle distributions post-collision, emphasizing the importance of entanglement in particle physics.

Physicists at Brookhaven National Laboratory and Stony Brook University discovered that particles produced in jets retain information about their origins in high-energy collisions, marking a notable advancement in the field.

The study aimed to determine how the distribution of hadrons in jets is influenced by the level of entanglement among quarks and gluons during their formation.

The findings suggest that maximal entanglement among quarks and gluons during fragmentation corresponds to a higher disorder in the resulting hadron distribution, observable in the jets.

This research opens new avenues for exploring quantum entanglement's role in hadron formation, particularly with the upcoming Electron-Ion Collider, which will enable detailed studies of quantum effects in high-energy collisions.

The Electron-Ion Collider will facilitate comparisons of jets from electron-proton and electron-nucleus collisions, further investigating quantum effects within protons and nuclei.

The study was supported by various institutions, including the Center for Frontiers in Nuclear Science and the DOE Office of Science, highlighting the collaborative effort in advancing nuclear physics research.
