Particle identification methods in high energy physics

This paper deals with two particle identification methods: dE/dx and Cherenkov detection. The dE/dx method is the most common technique used in conjunction with tracking in gaseous detectors. We systematically compare existing dE/dx data with various predictions available in the literature and judge the overall consistency. To my knowledge, this comparison was not done to date. There are two Cherenkov light emission detection techniques: the threshold and the Ring imaging methods. We want to discuss the recent trend in these techniques.
