diquarktriquark

Diquarktriquark is a theoretical concept in particle physics, referring to a composite system consisting of two diquarks and one triquark. A diquark is a hypothetical particle composed of two quarks, while a triquark is a hypothetical particle composed of three quarks.

The idea of diquarktriquark systems was first proposed in the 1970s as a possible explanation for the existence of certain exotic hadrons, which are particles made up of quarks and not described by the traditional quark model. These particles were seen to have unusual properties, such as a large positive charge and a high mass.

In a diquarktriquark system, the two diquarks are typically assumed to be in a spin-1 configuration, while the triquark is in a spin-1/2 configuration. The system is thought to be held together by the strong nuclear force, which attracts the quarks to each other.

Experimental searches for diquarktriquark systems have been performed in the search for exotic hadrons. The searches have focused on jet-like decay modes, where the diquarktriquark system is assumed to decay into a pair of jets, each consisting of a meson and a baryon. However, none of the searches have reported a clear observation of a diquarktriquark system.

Some research suggests that diquarktriquark systems may have interesting implications for the properties of these particles, such as their decay modes and lifetimes. However, the concept remains highly speculative and requires further study to confirm its validity.
