A comprehensive guide to the physics and usage of PYTHIA 8.3

🤖 Plain-English Summary

This manual describes the Pythia event generator, the most recent version of an evolving physics tool used to answer fundamental questions in particle physics. Finally, a chapter dedicated fully to the user is included towards the end, providing pedagogical examples of standard use cases, and a detailed description of a number of external interfaces.

🔑 Key Findings

• The program is most often used to generate high-energy-physics collision “events”, i.e.
• sets of particles produced in association with the collision of two incoming high-energy particles, but has several uses beyond that.
• The guiding philosophy is to produce and re-produce properties of experimentally obtained collisions as accurately as possible.
