About this document
QFT Summary by popot985 is a document available to read on EtoBox.
Quantum Field Theory (QFT) is a framework that integrates classical field theory, special relativity, and quantum mechanics to model subatomic particles and quasiparticles. In QFT, particles are viewed as excitations of fields, and their interactions are described through Lagrangians and Feynman diagrams. QFT underpins the Standard Model of particle physics, addressing interactions and incorporating techniques like renormalization to manage infinities in calculations.
