Help for Hepani

The most important

What you see time in animation is not exactly time physically. It only controls animation playing. In HEP process, for example, parton shower, time is meaningless. However, intermediates must occur in an order logically resonable, avoiding a not yet produced reactant producing its products. In our animation, we use the variable phase to deal with the order.

You'd better visit the website on PC, not a cell phone with a small screen and slow processors. Firefox, Chrome and Edge in latest versions are recommended.

Introduction

We are working for popularization of science. We try to produce animation from raw data simulated by HEP computational programs, such as pythia8. The animation does not strictly follow physical rules, however, clearly revealing how particles are produced, move or decay to other particles. Let more people see this page, inspiring more of us work hard for development of physics.

Generate animation

Before generating your own animation, we recommand you take a look at of our example. Visit our home, move your mouse over the icon and then over the item Start to see the example. If not familiar with the mouse option, just press the space key instead. Click here to get detailed information about animation generation or start the process by uploading a data file.
