Particle identification methods in high-energy physics

Abstract

This paper deals with two major particle identification methods: d E/d x and Cherenkov detection. In the first method, we systematically compare existing d E/d x data with various predictions available in the literature, such as the Particle Data Group recommendation, and judge the overall consistency. To my knowledge, such comparison was not done yet in a published form for the gaseous detectors used in high-energy physics. As for the second method, there are two major Cherenkov light detection techniques: the threshold and the Ring imaging methods. We discuss the recent trend in these techniques.
