The MIT Heavy Ion Event Display is the visualization of heavy ion collision events generated by the Hijing monte carlo simulation . The main purpose of this visualization is to give a better picture of a typical heavy ion collision event. It is not intended to give any new insight to current research. Rather, it is intended to help correct misconceptions related to the over-simplification of the heavy ion collision event (often by the disregard of special relativity).
The current version, EventDisplay1.0, has the following features.
Simulations are available as:

The simulation is also intended to highlight some of the points
that have not been given enough attention in the past.
Since the Hijing monte carlo simulation was not made for visualization of the collision events, information from the simulation is not enough to visualize the entire collision process. The information lacking from the simulation includes the incoming nuclei, the medium produced, hadronization, etc. We fill in this information based on the following assumptions:
Future development might come in several areas for better (closer to reality) visualization of the event. For example:
