Quantum field theory as a faithful image of nature

Quantum field theory, which represents the marriage of quantum mechanics with special relativity and provides the mathematical framework in which to describe the interactions of elementary particles, is developed to formulate modern particle physics. It is a powerful tool in depicting all fundamental processes except for gravitation. Here, I am going to, on a conceptual level, briefly clarify the foundations of quantum field theory. After laying basic mathematical and physical elements required for dissipative quantum field theory that combines both rigor and relevance in its early development, I will elaborate formal renormalization procedure implied by the dissipative approach to fundamental particle physics by taking the most studied φ⁴ theory (scalar field theory) as an example. Also, another modern idea known as BRST quantization dealing with the issue of gauge degree will be illustrated along with quantum electrodynamics.
