SUMMARY
The discussion focuses on the significance of pseudorapidity (η) in high-energy physics (HEP) experiments. Pseudorapidity is preferred over the polar angle (θ) for describing angular distributions due to its convenience and relevance to special relativity. Events in HEP experiments are often biased due to minimum bias triggers, which only capture a small fraction of collisions. Additionally, the phenomenon of pile-up, where multiple collisions occur in a single bunch crossing, is prevalent in experiments like ATLAS and CMS, with up to 40 collisions recorded simultaneously.
