# 30 years of jet quenching

## TL;DR

Over the past 30 years, jet quenching has evolved from a theoretical concept to a key experimental tool for probing the quark-gluon plasma in high-energy nuclear collisions.

## Contribution

This paper reviews three decades of jet quenching research, highlighting theoretical developments, experimental verification, and future prospects in QGP studies.

## Key findings

- Jet quenching established as a diagnostic for QGP properties.
- Experimental evidence confirms theoretical predictions.
- Advances enable detailed jet tomographic imaging of QGP.

## Abstract

In the last 30 years, the physics of jet quenching has gone from an early stage of a pure theoretical idea to initial theoretical calculations, experimental verification and now a powerful diagnostic tool for studying properties of the quark-gluon plasma (QGP) in high-energy heavy-ion collisions. I will describe my collaboration with Miklos Gyulassy in this exciting area of high-energy nuclear physics in the past 30 years on this special occasion of his 70th birthday and discuss what is ahead of us in jet tomographic study of QGP in heavy-ion collisions.
