multihadron

A multihadron is a bound state of multiple hadrons. Hadrons are composite particles that are made up of quarks and are subject to the strong force. This force, mediated by gluons, is responsible for binding quarks together to form hadrons. Examples of hadrons include protons, neutrons, and pions.

The simplest multihadron states are those consisting of just two hadrons. These can be further classified as either dibaryons, which are bound states of two baryons (like protons and neutrons), or exotic mesons, which are bound states of a meson and a baryon. Beyond these two-hadron states, more complex multihadron systems can exist, involving three or more hadrons.

The study of multihadron systems is a significant area of research in particle physics and nuclear physics. Theoretical frameworks such as quantum chromodynamics (QCD) are used to describe the interactions between quarks and gluons, which in turn govern the formation and properties of multihadron states. Experimental efforts often involve high-energy particle collisions to produce and detect these exotic states. The existence and properties of multihadron states provide crucial insights into the nature of the strong nuclear force and the structure of matter at its most fundamental level. Understanding these complex systems helps refine our models of the subatomic world.
