A hadron and a quantum field are distinct concepts in particle physics.
A hadron is a composite particle made up of quarks, which are elementary particles that carry fractional electric charge, and gluons, which are massless particles that mediate the strong nuclear force. Protons and neutrons are examples of hadrons. Hadrons are characterized by the fact that they experience the strong force and are subject to confinement, meaning they are always observed as bound states of quarks and/or gluons. Hadrons are subject to the laws of quantum mechanics, but they are not themselves quantum fields.
On the other hand, a quantum field is a fundamental concept in quantum field theory, which is a theoretical framework used to describe particles and their interactions. Quantum fields are fields that permeate all of spacetime and are associated with different types of particles. These fields are quantum mechanical in nature and follow specific rules of quantization. Particles are viewed as excitations or quanta of their respective fields.
In summary, a hadron is a composite particle composed of quarks and gluons and subject to the strong force, while a quantum field is a fundamental concept in quantum field theory that describes the behavior of particles and their interactions.
