Quantum field theory
Quantum field theory is a theoretical framework that combines quantum mechanics with special relativity to describe fields and their particle excitations. It provides the basis for modeling fundamental interactions in particle physics.
Quantum field theory is discussed in theoretical physics, particle physics, and high-energy physics.
Status
Quantum field theory underlies the Standard Model and is supported by extensive experimental results. Ongoing work addresses mathematical rigor, nonperturbative behavior, and extensions to include gravity.
