The Forces Governing Quark Interactions

Quarks are always confined within larger particles due to the strong nuclear force, which is mediated by particles known as gluons, acting as the 'glue' that holds them together. This force is much stronger than electromagnetic interactions but only operates over short distances, ensuring quarks cannot exist in isolation. In addition, quarks possess a property called color charge, which, unlike visual color, relates to their interactions under the strong force, allowing for combinations that result in color-neutral particles. Extreme conditions, such as those found in particle accelerators, can lead to phenomena like quark-gluon plasma, where quarks are liberated from their confinement, providing insights into fundamental conditions shortly after the Big Bang.
