A comprehensive guide to the physics and usage of PYTHIA 8.3

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.

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

This work deepens our understanding of the fundamental laws governing the universe, from subatomic particles to cosmic structures.
