    Introduction Quark-Gluon Plasma (QGP) is an extreme state of matter believed to have existed microseconds after the Big Bang. It’s a hot, dense phase of quantum chromodynamics (QCD) where quarks and gluons—fundamental particles of the strong interaction—roam free rather than being confined within hadrons (like protons and neutrons). The study of QGP provides crucial insights…

    Introduction Quantum Chromodynamics (QCD) is a theory in theoretical physics t hat describes the interactions of quarks and gluons, the fundamental particles that make up protons, neutrons, and other particles. The term “chromodynamics” comes from the Greek word “chroma,” meaning color, as quarks carry a type of charge known as “color charge.” Fundamental Concepts and…

    Introduction Mesons are a category of subatomic particles composed of a quark and an antiquark pair, bound together by the strong nuclear force. They are classified as bosons due to their integral spin. Basic Properties of Mesons Mesons are defined by the composition of a quark-antiquark pair. The quark content determines the properties of the…

    Introduction In the realm of particle physics, Hadrons are a class of particles that are made up of quarks, antiquarks, and gluons, bound together by the strong nuclear force. They are among the most commonly observed particles in nature, with protons and neutrons, which make up atomic nuclei, being examples of hadrons. Classification of Hadrons…

    Introduction Gluons are elementary particles that mediate the strong interaction, one of the four fundamental forces of nature. They are the force carriers of the strong nuclear force, much like photons are for the electromagnetic force. Properties of Gluons Gluons are bosons, particles with integer spin, and they possess a property known as color charge.…

    Introduction Quantum Field Theory (QFT) is a theoretical framework that combines the principles of quantum mechanics and special relativity to describe the behavior of quantum particles and fields. It is the basis for our understanding of elementary particle physics, and it underpins the standard model of particle physics. Basics of Quantum Fields In QFT, particles…

    Introduction Quarks are elementary particles that make up protons and neutrons, which in turn are the building blocks of atomic nuclei. The existence of quarks was first proposed by Murray Gell-Mann and George Zweig in 1964. Types of Quarks Six types, or “flavors,” of quarks have been identified: up, down, charm, strange, top, and bottom.…

    Introduction The strong nuclear force, also known as the strong interaction or the strong force, is one of the four fundamental forces of nature. It is the force responsible for binding protons and neutrons together in atomic nuclei. The strong force is approximately 100 times stronger than the electromagnetic force, a million times stronger than…
