Welcome to Experimental High Energy Physics (EHEP) LAB

Introduction

Why "High" energy?

In order to "see" matter at small distances, one needs to "microscope" with high resolving power. Accelerator is one of excellent experimental tools invented in modern science.

What is high energy physics?
Questions addressed include:
- What is the "Standard Model?"
- Why do we believe it is correct?
- Is there anything wrong with it?
- What next?
In a nutshell, a theorist would be tempted to say "fundamental symmetries", but we infer these from constituents and interactions seen experimentally.
