Right now, it depends on WHO is doing the counting. Quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic...
Quantum field theory, a revolutionary concept, challenges our traditional understanding of particles. It suggests that the entities we’ve long considered as ‘things’—protons, neutrons, and quarks—are not fundamental entities. Instead, according to...
