Abstract
The Standard Model of particle physics is a theory concerning the
electromagnetic, weak, and strong nuclear interactions, which mediate the
dynamics of the known subatomic particles. Still, the Standard Model falls
short of being a complete theory of fundamental interactions because it
does not incorporate the physics of dark energy nor of the full theory of
gravitation as described by general relativity. The Standard Model is a
Quantum Field Theory (QFT) that describes the fundamental particles
(matter fields) in nature and the way in which they interact. In the quantum
field theory, nature consists of a specific number of fields that fill the
space-time and obey the rules of quantum mechanics and special theory of
relativity. These fields have states of excitations that show up as particles.
Nevertheless, the standard model is important to theoretical and experimental particle physicists alike. In quantum Mechanics, particles
number is a conserved quantity, while in quantum field theories we might.
