In particle physics, a hadron (/ ˈhædrɒn / ⓘ; from Ancient Greek ἁδρός (hadrós) 'stout, thick') is a composite subatomic particle made of two or more quarks held together by the strong interaction. They are analogous to molecules, which are held together by the electric force.

Hadon of Ancient Opar is a fantasy novel by American writer Philip José Farmer, first published in paperback by DAW Books in April 1974, and reprinted three times through 1983. The first British edition was published by Magnum in 1977; it was reprinted by Methuen in 1993.

The meaning of HADRON is any of the subatomic particles (such as protons and neutrons) that are made up of quarks and are subject to the strong force.

A hadron, in particle physics, is any subatomic (smaller than the atom) particle or antiparticle which is made of quarks. Quarks are fundamental particles which among other properties have an electrical charge and a name (e.g. 'up', 'down', 'strange'). The electrical charge of a single quark is always a fraction (e.g. 2/3). [1] .

When a mysterious enemy strikes from out of the wilds, King Hadon must lead his golden city against the most perilous threat it has ever faced. As he embarks on a mission to confront the danger, Hadon runs headlong into a maze of plots and intrigues lurking in the ages-old tunnels deep beneath the city.
