QCD factorization and quantum mechanics

Abstract

Abstract – It is unusual to find quantum chromodynamics (QCD) factorization explained in the language of quantum information science. However, we will discuss how the issue of factorization and its breaking in high-energy QCD processes relates to phenomena like decoherence and entanglement. We will elaborate with several examples and explain them in terms familiar from basic quantum mechanics and quantum information science. This article is part of the theme issue ‘Quantum technologies in particle physics’.
