ANTIPARTICLE Meaning and
Definition
-
An antiparticle refers to a subatomic particle that possesses the same mass but carries the opposite charge compared to its corresponding particle in the standard model of particle physics. When these two particles meet, they can annihilate each other, thereby releasing energy. Antiparticles were first proposed by physicist Paul Dirac in 1928 as he developed the Dirac equation to describe the behavior of relativistic electrons. According to this equation, for every particle, there exists an antiparticle with the same mass and opposite charge.
Antiparticles are a fundamental concept in particle physics and quantum field theory. They are considered a crucial component of the antiparticle hypothesis, which states that for every type of matter particle, an antiparticle with corresponding properties exists. Some examples of antiparticles include the positron (the antiparticle of the electron) and the antiproton (the antiparticle of the proton). Antiparticles can be generated through various processes including particle collisions, high-energy particle accelerators, and natural phenomena such as cosmic rays.
The study of antiparticles and their interactions has had significant implications in the field of particle physics, helping to deepen our understanding of the fundamental building blocks of the universe and the laws that govern them. Antiparticles have practical applications in medicine as well, with positron emission tomography (PET) being a notable example that utilizes the properties of positrons to provide detailed medical imaging.

Etymology of ANTIPARTICLE
The word "antiparticle" was coined in the early 1930s by renowned physicist Paul Dirac, to describe the concept of a particle with the same mass but opposite charge as another particle. Dirac introduced the term in his work on the equation that described relativistic electrons, known as the Dirac equation.
The prefix "anti-" in "antiparticle" denotes the opposite or contrary nature of the particle. In this case, it signifies the opposite electric charge of the antiparticle compared to the corresponding particle. For example, the antiparticle of an electron, called the positron, has a positive charge (+1) as opposed to the negative (-1) charge of an electron.
Dirac's formulation led to the prediction and subsequent discovery of several antiparticles, such as the positron (antiparticle of the electron) and the antiproton (antiparticle of the proton).
