Pair production Print

What happens when matter meets antimatter along its path? The answer is that the process of annihilation occurs. However, high-energy photons can produce both matter and antimatter in the pair-production process. This illustration shows an example of the production of an electron-positron pair. The picture is part of the science popularization book "From Black Bodies to the Dark Energy of the Universe." The drawing was produced using the watercolor technique on paper. The lines of different colors illustrate the formation of the pair of particles in a process that occurs, for example, when cosmic radiation interacts with the Earth's high atmosphere.
