Quantum fields offer a consistent framework for particle physics from "summary" of The Quantum Theory of Fields by Steven Weinberg,Weinberg S
The development of a consistent theoretical framework for particle physics has been a long-standing goal of physicists. Quantum field theory has emerged as a powerful tool for achieving this goal, providing a mathematical formalism that can describe the behavior of particles and their interactions in a consistent and unified way. In the quantum field theory framework, particles are not treated as fundamental entities but rather as excitations of underlying fields that permeate all of space. These fields are represented mathematically by operators that satisfy certain commutation relations, allowing for the quantization of the theory. By quantizing the fields, one can describe the creation and annihilation of particles, as well as their interactions with each other. This approach allo...
